51:9-16 The people whom Christ has redeemed with his blood, as well as by his power, will obtain joyful deliverance from every enemy. He that designs such joy for us at last, will he not work such deliverance in the mean time, as our cases require? In this world of changes, it is a short step from joy to sorrow, but in that world, sorrow shall never come in view. They prayed for the display of God's power; he answers them with consolations of his grace. Did we dread to sin against God, we should not fear the frowns of men. Happy is the man that fears God always. And Christ's church shall enjoy security by the power and providence of the Almighty.
16. Addressed to Israel, embodied in "the servant of Jehovah" (Isa 42:1), Messiah, its ideal and representative Head, through whom the elect remnant is to be restored.
put my words in thy mouth—true of Israel, the depository of true religion, but fully realized only in Israel's Head and antitype, Messiah (Isa 49:2; 50:4, 5; 59:21; De 18:18; Joh 3:34).
covered … in … shadow of … hand—protected thee (see on Isa 49:2).
plant—rather, "fix" as a tabernacle; so it ought to be rendered (Da 11:45). The "new creation," now going on in the spiritual world by the Gospel (Eph 2:10), and hereafter to be extended to the visible world, is meant (Isa 65:17; 66:22; compare Isa 13:13; 2Pe 3:10-13).
Zion—Its restoration is a leading part in the new creation to come (Isa 65:17, 19).
