Isaiah 44:23

“Sing, O ye heavens, for the Lord hath done it, &c.] Done what he promised, the forgiveness of the sins of his people, and the redemption of them. So the Targum, “because the Lord hath wrought redemption for his people.” The Vulgate Latin version adds, “mercy”f864; and so the Septuagint version, “because God hath had mercy on Israel”f865; and therefore the heavens are called upon to sing on this occasion, as the angels of heaven did when the Redeemer was born, and who rejoice at the salvation of God’s elect, (<420213>Luke 2:13,14 15:10): shout, ye lower parts of the earth; the earth, which is low in comparison of the heavens; the inhabitants of it, especially the Gentiles, which dwelt in the…”

“Call to inanimate nature to praise God; for it also shall share in the coming deliverance from "the bondage of corruption" (Rom 8:20-21). done it--effected redemption for both the literal and spiritual Israel. lower parts, &c.--antithetical to "heavens"; "mountains," "forest," and "tree," are the intermediate objects in a descending gradation (see Psa 96:11-12).”

“Sing, O ye heavens - (see Isaiah 42:10). It is common in the sacred writings to call on the heavens, the earth, and all created things, to join in the praise of God on any great and glorious event (see Psalms 96:1, Psalms 96:11-12; Psalms 148:1-14) The occasion of the joy here was the fact that God had redeemed his people - a fact, in the joy of which the heavens and earth were called to participate. An apostrophe such as the prophet here uses is common in all writings, where inanimate objects are addressed as having life, and as capable of sharing in the emotions of the speaker. Vitringa has endeavored to show that the various objects here enumerated are emblematic, and that by the heavens…”

“Sing - By such invitations to the senseless creatures, he signifies the transcendent greatness of this mercy, sufficient to make even the stones, if it were possible, to break forth into God's praises. Isaiah 44:25”

“44:23 All creation is called to celebrate God’s redemption of Israel (cp. 1:2).”

“Sing: Isa 42:10-12, Isa 49:13, Isa 55:12, Isa 55:13; Psa 69:34, Psa 96:11, Psa 96:12, Psa 98:7, Psa 98:8; Jer 51:48; Luk 2:10-14; Rev 5:8-14, Rev 12:12, Rev 18:20, Rev 19:1-6 glorified: Isa 26:15, Isa 49:3, Isa 60:21; Eze 36:1, Eze 36:8, Eze 39:13; Eph 1:6, Eph 1:7, Eph 3:21; Th2 1:10-12; Pe1 4:11 Isaiah 44:24”

“There is already good ground, therefore, for exuberant rejoicing; and the reply of the church to these words of divine consolation is as follows: "Exult, O heavens; for Jehovah hath accomplished it: shout, ye depths of the earth; break out, ye mountains, into exulting; thou forest, and all the wood therein: for Jehovah hath redeemed Jacob, and He showeth Himself glorious upon Israel." All creation is to rejoice in the fact that Jehovah has completed what He purposed, that He has redeemed His people, and henceforth will show Himself glorious in them. The heavens on high are to exult; also the depths of the earth, i.e., not Hades, which would be opposed to the prevailing view of the Old…”
