Then was our mouth filled with laughter,.... Who before mourned, and hung their harps on the willows, and could not sing the Lord's song in a strange land; but now, as their hearts were filled, with joy, this was externally and visibly seen in their countenances, and expressed with their mouths and by outward gestures; it was so great, they could not contain it, to which respect is had, Isa 35:10. It may be rendered, "then shall our mouth be filled with laughter" (q); that is, when we awake, says Arama; or rather when the captivity is returned, either in a literal or in a spiritual sense, both being matter of great joy: the Midrash says, this will be in the world to come, and not in this; and our tongue with singing; the praises of God, and the songs of Zion; then said they among the Heathen, the Lord hath done great things for them; it was taken notice of by the Chaldeans, among whom they had been captives, and by all the nations round about: and it was wonderful to them, that Cyrus, an Heathen prince, of his own motion and will, should at once, and without any price or reward, let them go, and send them into their own country to rebuild their temple; and with them the vessels of the Lord's house, that had been taken away by the king of Babylon; and order men to help them, with gold and silver, and goods and cattle, Ezr 1:1. Likewise the conversion of the Jews, and the restoration of them to their own and in the latter day, will be observed by the Gentiles with wonder, and as the work of God, Eze 36:35. (q) "replebitur", Musculus, Gejerus; "implebitur", Schmidt; so the Targum, Syr. Arab.
