Psalms 126 - Dummelow's Commentary on the Bible

Turned again the captivity of Zion] either, brought back the exiles who returned to Zion, or, turned again the fortunes of Zion, i.e. perhaps, set her free from foreign yoke.

A song of those who have been redeemed (from exile), and a hopeful prayer for those who have not yet returned.

Weepeth] suggestive of the patient labour of the sower. Bearing precious seed] better, 'bearing a measure of seed.' The sower carried the seed in a cloth tied to his body—this cloth full is a 'measure.'
