(19) I will plant in the wilderness.--A picture as of the Paradise of God (Isaiah 51:3), with its groves of stately trees, completes the vision of the future. The two groups of four and three, making up the symbolic seven, may probably have a mystic meaning. The "shittah" is the acacia, the "oil tree" the wild olive, as distinguished from the cultivated (Romans 11:17), the "fir tree" is probably the cypress, the "pine" stands for the plane, always--as in the opening of Plato's Ph?drus, and the story of Xerxes in Herod. vii. 31,--the glory of Eastern scenery and the "box-tree" is perhaps the larch, or a variety of cedar. The "myrtle" does not appear elsewhere in the Old Testament till after the exile (Nehemiah 8:15; Zechariah 1:8; Zechariah 1:10-11), but then it appears as if indigenous. It supplies the proper name Hadassah (Esther) in Esther 2:7.

Verse 19. - I will plant in the wilderness the cedar, etc. The "glory of Lebanon," the "excellency of Carmel and Sharon" (Isaiah 35:2), shall be given to the "wilderness," wherein Israel dwells. The trees named are the choicest of Syria and Palestine, viz. the cedar (erez). the great glory of Libanus; the acacia (shittah), abundant in the Jordan valley; the myrtle (hadas),whieh grew on the hills about Jerusalem (Nehemiah 8:15); the olive, cultivated over the whole country; the fir (berosh), or juniper. a product of Lebanon (2 Chronicles 2:8); the plane (tidhar), a tree far from uncommon in Coele-syria, sometimes growing to a great size; and the sherbin (teasshur), a sort of cedar, remarkable for the upward tendency of its branches. The list of names shows a writer familiar with the Palestinian region, but not familiar with Babylonia.

41:10-20 God speaks with tenderness; Fear thou not, for I am with thee: not only within call, but present with thee. Art thou weak? I will strengthen thee. Art thou in want of friends? I will help thee in the time of need. Art thou ready to fall? I will uphold thee with that right hand which is full of righteousness, dealing forth rewards and punishments. There are those that strive with God's people, that seek their ruin. Let not God's people render evil for evil, but wait God's time. It is the worm Jacob; so little, so weak, so despised and trampled on by every body. God's people are as worms, in humble thoughts of themselves, and in their enemies' haughty thoughts of them; worms, but not vipers, not of the serpent's seed. Every part of God's word is calculated to humble man's pride, and to make him appear little in his own eyes. The Lord will help them, for he is their Redeemer. The Lord will make Jacob to become a threshing instrument. God will make him fit for use, new, and having sharp spikes. This has fulfilment in the triumphs of the gospel of Christ, and of all faithful followers of Christ, over the power of darkness. God has provided comforts to supply all their wants, and to answer all their prayers. Our way to heaven lies through the wilderness of this world. The soul of man is in want, and seeks for satisfaction; but becomes weary of seeking that in the world, which is not to be had in it. Yet they shall have a constant supply, where one would least expect it. I will open rivers of grace, rivers of living water, which Christ spake of the Spirit, Joh 7:38,39. When God sets up his church in the Gentile wilderness, there shall be a great change, as if thorns and briers were turned into cedars, and fir-trees, and myrtles. These blessings are kept for the poor in spirit, who long for Divine enlightening, pardon, and holiness. And God will render their barren souls fruitful in the grace of his Spirit, that all who behold may consider it.I will plant in the wilderness the cedar, the shittah tree,.... Where such trees had not used to grow, but in Lebanon, and such like places. The "shittah tree" is thought to be a kind of cedar; it is the same of which is the "shittim wood" mentioned in Exodus 25:5 and is so called by the Targum here:

and the myrtle, and the oil tree; about the former there is no difficulty, and one would think there should be none about the latter, and that the olive tree is meant; but Kimchi thinks that is not certain, and supposes the pine tree is meant; and observes that the olive tree is distinguished from this oil tree in Nehemiah 8:15, as indeed it is; and is by our translators there rendered the pine tree, which they take to be meant by another word in the next clause:

I will set in the desert the fir tree, and the pine, and the box tree together; what we here render the "pine" the Targum interprets it of the "elm", and so the Vulgate Latin version: now by all these are figuratively meant converted persons in the Gentile world, in whom as great a change was wrought, as if, instead of briers and thorns, came up such trees as these; and who, by the grace of God, were made as goodly and beautiful as some of these trees were; as odorous and of as sweet a scent in their graces and duties as others; and as profitable and fruitful in grace and good works like others of them; and comparable to them, as being some of them evergreen, durable, and incorruptible; because of their perseverance in grace and holiness.
