The psalm starts by recalling the day when the Lord brought back the captives of Zion. It was so unbelievable that the people felt as if they were dreaming. Their mouths were filled with laughter and their tongues with shouts of joy, and among the nations it was said that the Lord had done great things for them. The people confirm it: the Lord has done great things for us, and we are glad.
Verse 4 changes tone and time. The joy of the past has not removed the present need, and the people pray: restore our fortunes, O Lord, like the streams in the Negeb. In that dry region of southern Judah, the dry riverbeds fill suddenly with water after rain and transform the desert.
Verses 5 and 6 end with a picture of farm work. Those who sow in tears shall reap with shouts of joy. He who goes out weeping, bearing the seed, shall come home with shouts of joy, carrying his sheaves. Sowing was costly, because it meant giving up grain needed for food; but God promises a harvest of joy.
