Psalms 126:4

Turn again our captivity] perhaps, 'bring back the exiles.' As the streams in the south] i.e. like the hill streams in the arid S. land of Judah (the Negeb), dry for a time in summer but becoming suddenly swollen torrents in the rains of autumn.

5. A proverb—sow in tears, reap with ringing cries. The reference may be to the difficulties amid which the pioneers of the return from exile had to work: cp. Ezr and Neh.
