Charles H. Spurgeon on Psalms 126:3

The Lord hath done great things for us, etc. This verse is the marrow of the whole psalm, occasioned by the return of God's people out of Babel's captivity into their own country. Their deliverance was so great and incredible that when God brought it to pass they were as men in a dream, thinking it rather a dream, and a vain imagination, than a real truth. 1. Because it was so great a deliverance from so great and lasting a bondage, it seemed too good to be true. 2. It was sudden and unexpected, when they little thought or hoped for it...3. All things seemed desperate, nothing more unlikely, or impossible rather. 4. The manner was so admirable (without the counsel, help, or strength of man: nay, it was beyond and against all human means); that they doubt whether these things be not the dreams of men that are awake. —Thomas Taylor (1576-1632), in "A Mappe of Pwme."
