Charles H. Spurgeon on Psalms 126:1

We were like them that dream. The words should rather be translated, "We are like unto those that are restored to health." The Hebrew word signifies to recover, or, to be restored to health. And so the same word is translated in Isa 38:1-22, when Hezekiah recovered, he made a psalm of praise, and said, "O Lord, by these things men live, and in all these things is the life of my spirit: so wilt thou recover me, and make me to live." It is the same word that is used here. Thus Cajetan, Shindior, and others would have it translated here; and it suits best with the following words, "Then were our mouths filled with laughter, and our tongues with praise." When a man is in a good dream, his mouth is not filled with laughter, nor his tongue with praise: if a man be in a bad dream, his mouth is not filled with laughter, nor his tongue with praise; but when a man is restored to health after a great sickness, it is so. —William Bridge, 1600-1670.
