Psalm 126 discusses joy experienced by God's people in the past, present, and future. It describes how they laughed and sang for joy when God restored the fortunes of Zion and brought the exiles home from Babylon. In the present, the psalmist calls on God to restore their fortunes again through bringing rains to the drought-stricken land so that those who sow in tears may reap with joyful song. Looking to the future, the psalm expresses confidence that God will continue to act in ways that bring joy, as he has done in the past.
