“Sing!

O heavens!

Yahweh has done it.

Shout!

O depths of the earth!

Break forth into singing!

O mountains!

O forest!

Every tree in it!

Yahweh has redeemed Jacob.

He will be glorified in Israel!”

Second Isaiah has this chant of joy. The heavens were to sing about what Yahweh has done. The depths of the earth should shout. The mountains and the forests, with all its trees, should break into singing. Yahweh has redeemed Jacob so that he should be glorified in Israel.
