"Then was our mouth filled with laughter, And our tongue with singing: Then said they among the nations, Jehovah hath done great things for them." — Psalms 126:2 (ASV)

Singing. — As is frequent concerning the restoration in Isaiah: Isaiah 42:11; Isaiah 44:23; Isaiah 54:1; and others.

Has done. — See the margin, and compare to Joel 2:21.
