Matthew Henry Commentary Psalms 126:1-3

"When Jehovah brought back those that returned to Zion, We were like unto them that dream. Then was our mouth filled with laughter, And our tongue with singing: Then said they among the nations, Jehovah hath done great things for them. Jehovah hath done great things for us, [Whereof] we are glad." — Psalms 126:1-3 (ASV)

It is good to observe how God's deliverances of the church are for us, that we may rejoice in them. And how ought redemption from the wrath to come, from the power of sin and of Satan, to be valued! The sinner convinced of his guilt and danger, when by looking to a crucified Saviour he receives peace to his conscience, and power to forsake his sins, often can scarcely believe that the prospect which opens to him is a reality.
