Charles H. Spurgeon on Psalms 126:2

Then was our mouth filled with laughter, etc. It was thus in the valley of Elah, where Goliath fell, and Philistia fled. It was thus at Baal Perazim. It was thus when one morning, after many nights of gloom, Jerusalem arose at dawn of day, and found Sennacherib's thousands a camp of the dead. And it has all along been the manner of our God.

"The Lord has wrought mightily

In what he has done for us;

And we have been made glad."

Ever do this till conflict is over! Just as thou dost with the streams of the south, year by year, so do with us —with all, with each. And we are confident thou wilt; we are sure that we make no vain boast when we sing this psalm as descriptive of the experience of all thy pilgrims and worshippers. —Andrew A. Bonar, in "Christ and his Church in the Book of Psalms," 1859.
