And I have put my words in thy mouth, and I have covered thee in the shadow of mine hand, that I may plant the heavens, and lay the foundations of the earth, and say unto Zion, Thou art my people.
And I have put my words in thy mouth - Addressed, to Israel, embodied in 'the servant of Yahweh' (Isaiah 42:1), Messiah, its ideal and representative Head, through whom the elect remnant is to be restored. God 'put His words in the mouth' of Israel, the depositary of true religion, primarily; but fully, in the mouth of Israel's Head and antitype, Messiah (Isaiah 49:2; Isaiah 50:4-5; Isaiah 59:21; Deuteronomy 18:18 is the fundamental passage: cf. "He whom God hath sent, speaketh the words of God, because God giveth not the Spirit by measure unto Him," John 3:34).
And have covered thee in the shadow of mine hand - I have protected thee (note, Isaiah 49:2).
That I may plant the heavens. The Hebrew, naata` (H5193), to plant, is also metaphorically used for to 'fix' as a tabernacle (Daniel 11:45). Compare Psalms 19:4, "In them (the heavens) hath He set a tabernacle for the sun." The "new creation," now going on in the spiritual world by the Gospel (Ephesians 2:10), and hereafter to be extended to the visible world, is meant (Isaiah 65:17; Isaiah 66:22: cf. Isaiah 13:13; 2 Peter 3:10-13).
And say unto Zion. Its restoration is a leading part in the new creation to come (Isaiah 65:17-19).
