Isaiah 44:23
Sing, O ye heavens; for the LORD hath done it: shout, ye lower parts of the earth: break forth into singing, ye mountains, O forest, and every tree therein: for the LORD hath redeemed Jacob, and glorified himself in Israel. Sing, O ye heavens; for the LORD hath done it: shout, ye lower parts of the earth: break forth into singing, ye mountains, O forest, and every tree therein: for the LORD hath redeemed Jacob, and glorified himself in Israel.
The call goes out to all creation to break into joyful singing, to the heavens to sing, to the lower parts or depths of the earth to shout, and to the mountains and the forest and every tree in it to break forth into singing. The summons rests on what the Lord has done, for he has redeemed Jacob and glorified himself in Israel. His saving work displays his glory, and that display gives all creation reason to praise him.
In its setting this redemption means he formed Jacob and Israel as his servants and has not forgotten them. It means he has blotted out their transgressions as a thick cloud and their sins as a cloud, and calls them to return to him because he has redeemed them. The verse stands among the promises of Isaiah 44 and 45 about what the Lord has done and will do and what he has covenanted to do, and those chapters give encouragement. These promises are to be appreciated, and following on to know the Lord brings knowledge of his coming work.
The verse reveals God carrying forward a special work in which, because he is good and gracious, he supplies the necessities of his created universe. He satisfies the desires of the soul together with temporal needs such as moistening dry lips and cooling the tongue, supplying spiritual necessities and temporal needs together. He is glorified in Israel through his work through his people, and this brings glory to his name. Their life and conduct should therefore display his character rather than human ideas or self-confident human management that puts him aside.
