Matthew Henry: A laughter of joy in God

Psalm 126:2 Then our mouth was filled with laughter,
and our tongue with shouts of joy;
then they said among the nations,
Lord has done great things for them.”
The Lord has done great things for us;
we are glad.

They that were laughed at, now laugh, and a new song is put into their mouths. It was a laughter of joy in God, not scorn of their enemies.

Matthew Henry, as quoted in Spurgeon’s “Treasury of David”
