Jesus foretold - Isaiah 1: 1 - 10
(Bible quotes are from the New English Bible, unless otherwise noted.)

V 1.
Then a shoot shall grow from the stock of Jesse,
and a branch shall spring from his roots
NIV.  A shoot will come up from the stump of Jesse;
from his roots a branch will bear fruit.
NLT. Out of the stump of David's family will grow a shoot - yes, a new Branch bearing fruit from the old root.

A shoot from the stump of Jesse - foretelling of the coming of Jesus who was descended from Jesse, King David's father.  Jesus' genealogy is given in Matthew 1.  The names of most of the people mentioned in that genealogy would have been familiar to teh Jews of matthew's day.  They would have known the stories surrounding those names as well as we know the stories of Biblical heroes or the 'heroes' of our own families.  On hearing that genealogy they would have known exactly where Jesus fitted in.

In the Australian bush it is not uncommon to see healthy young saplings growing up from the seemingly dead stump or the fallen trunk of a tree.  This is the picture Isaiah uses to show that, although David's house seemed to have ended, new growth can come unexpectedly.  And it did!

Quest Study Bible note, p 952.  A picture of a family tree chopped down.  God had promised David, Jesse's son, that his descendants would rule forever (2 Samuel 7: 12 - 16).  But when those descendants failed to meet the conditions of teh promise, the tree was cut down.
                                                Isaiah played on the picture of a family tree.  From the stump of Jesse a new branch would sprout, a future Messiah whom we now know as Jesus Christ. (Matthew 16: 16, Romans 1: 2 - 4).  Since the Messiah would be a branch of Jesse's family tree, the word branch became a Messianic title.  The Branch of the Lord also suggests the spiritual fruit produced by the Messiah.

New Bible Commentary, p 641.  The tree, felled but not finished, makes a telling contrast to the razed forest of Assyria (Ch. 10: 33 - 34).  In Isaiah 6:13 the tree stump was Israel, living on the remnant;  here it is the house of David, and its growing-point is one man.

V 2.

The Spirit of the Lord shall rest upon him, a spirit of wisdom and understanding,
a spirit of counsel and power,
a spirit of knowledge and the fear of the Lord.

The one to come would be fully equipped by the Holy Spirit for his role.  Luke 4: 1 & 14 tell us that Jesus was full of the Holy Spirit and was armed with the power of the Spirit (NLT.  full of the Holy Spirit).  At his baptism the Spirit descended on him like a dove (Luke 3: 22. Mark 1: 10, Matthew 3: 16, John 1: 33).

The qualities or gifts that would be given to this special person by the Holy Spirit, according to Isaiah, were:
wisdom
understanding
counsel
power (NLT: might)
knowledge and fear of the Lord

It is important for Christian leaders - and would be good for any leaders - to have wisdom and understanding, knowledge of God and a healthy respect for God so that their power is used properly.  All these were qualities Jesus had, making him the 'perfect king'

New Bible Commentary, p. 641. The Spirit, not royal birth alone, fits him for office, like the judges and early kings so that he is a Solomon, Gideon and David in one, yet not partially or fitfully endued, but abidingly and richly.
(Some examples from the Old Testament of the Spirit fitting people for office: 
Judges 3: 10; 6: 34, when the spirit of the Lord came on Othneil and made him a judge to lead Israel and on Gideon to give him power and strength to lead the Israelites to victory; and
1 Samuel 10:10, when the Spirit fell on king Saul and led him to prophesy, and
1 Samuel 16: 13, when Samuel anointed David and the spirit of the Lord filled David and stayed for the rest of his life.)
The gifts are three-fold: wisdom and understanding for government, counsel and power for war, and knowledge and the fear of the Lord for spiritual leadership.

NB: 'fear' in this sense means 'awe' or respectful obedience, not being scared or frightened of the Lord.

Vs 3 - 5.

He shall not judge by what he sees
nor decide by what he hears;
he shall judge the poor with justice
and defend the humble in the land with equity;
his mouth shall be a rod to strike down the ruthless,
and with a word he shall slay the wicked.
Round his waist he shall wear the belt of justice,
and good faith shall be the girdle round his body.
NLT. He will delight in obeying the Lord.  He will never judge by appearance, false evidence or hearsay.  He will defend the poor and the exploited. He will rule against the wicked and destroy them with the breath of his mouth.  He will be clothed with fairness and truth.

The perfect king - the Messiah - would delight in 'fearing' God - he would delight in obeying God and in doing God's work.  He would make judgements based on his wisdom, understanding of the situation and knowledge of God, and not relying on what his eyes see and his ears hear.  Our senses sometimes give us warped information - we need to rely on the guidance of the Holy Spirit (which can come to us through reading and study of God's word and through discussion and advice from other Christians) before jumping to conclusions.

He will bring justice to the poor and opressed.  This is God's 'heart' - according to his love for all of his creation, he deeply desires justice for all people.  It would be a key role of the Messiah to bring about justice.  Jesus' life on earth modelled this and it is teh task of God's people, Jesus' followers, to continue it until he comes again.

Quest Study Bible note, p. 952.  Isaiah anticipated a time when Christ would completely right all wrongs.  While on earth, Christ began to establish justice by what he said and taught.  His written word continues to bring justice today whenever it is obeyed.  Though justice on earth has begun, the scales won't be completely balanced until Christ returns the second time.

New Bible Commentary, p 641.  The delight of 3a carries the implication that the fear of the Lord is fragrant to him.  Vs 3 - 5 show these powers exercised in turn, making him the guide, guardian and example of his people.  It is already emerging in v.4b that he is supernaturally endowed......

Vs. 6 - 9.

Then the wolf shall live with the sheep,
and the leopard lie down with the kid;
the calf and the young lion shall grow up together,
and a little child shall lead them;
the cow and the bear shall be friends,
and their young shall lie down together.
The lion shall eat straw like cattle;
the infant shall play over the hole of the cobra,
and the young child shall dance on the viper's nest.
They shall not hurt or destroy in all my holy mountain;
for as the waters fill the sea,
so shall the land be filled with the knowledge of the Lord.

Here is a picture of an ideal world - just the way God intended it to be - the Garden of Eden again!  A picture of complete peace, joy, and fellowship all over the world with trust between peop[le and where even the animals stop preying on each other.

Paul, in romans 8: 21 describes a hope - a looking forward - to this perfect world. ...yet always there is hope, because the universe itself is to be freed from the shackles of mortality and enter upon the liberty and splendour of the children of God. (NLT. All creation anticipates the day when it will join God's children in glorious freedom from death and decay.)

New Bible Commentary, p 641-2.  In this idyllic scene the title 'Prince of Peace' is perfectly unfolded.  Significantly, peace is hard-won;  it follows judgement (v 4b) and springs from righteousness (v 5), true to the sequence expounded in Isaiah 32: 17 (when righteousness shall yield peace
and its fruit be quietness and confidence forever).

Its heart, however, is the relationship expressed as the knowledge of the Lord.  As a picture this is unforgettable and expresses reconciliation, concord and trust with supreme effectiveness.  The reign of Christ already produces this kind of transformation in teh sphere of human character, and will ultimately change the whole creation.  Whether this will be realised literally as depicted here is another mstter; it seems better to view this as an earthly expression of the 'new heavens and ...new earth (mentioned in Isaiah 65: 17, 25) in which variety will not be enmity, and the weak will be the complement, no longer the prey, of the strong.

Quest Study Bible note p 952.  Some believe this scene pictures a future time of universal peace - the Millenium - an earthly kingdom to be set up by Christ when he returns (see Revelation 20: 1 - 6).  Others think wolves may describe sinners who turn from their predatory ways to live in harmony with God's people, the lambs.  This could refer to spiritual changes that bring individuals into God's kingdom now.

V 10.
On that day a scion from the root of Jesse
shall be set up as a signal to the peoples;
the nations shall rally to it,
and its resting place shall be glorious.

The Messiah - the perfect king sent by God - will be the person around whom this whole united creation revolves.  Teh cross of Christ has become a signal - or symbol - for God's people to rally around.  The resting place of Christ is certainly glorious!.

New Bible Commentary, p 642.  V 10, bursts the bounds of nationality, while emphasising that  salvation is in only one name under heaven (compare with Acts 4: 12  There is no salvation in  anyone else at all, for there is no other name under heaven granted to men, by which we may receive salvation).  This king is both root and offspring of the royal house.  note the voluntary response of the nations........
