Albert Barnes Commentary Psalms 128:4

"Behold, thus shall the man be blessed That feareth Jehovah." — Psalms 128:4 (ASV)

Behold, that thus shall the man be blessed ... - As if he had said, “Look upon this picture. See the farmer cultivating his fields; see him gathering in the grain; see him at his own table calmly, quietly, and gratefully enjoying the fruit of his toil. Look upon that picture of a happy family—numerous, cheerful, beloved—giving promise of upholding the name of the family in future years—and see all this as coming from the Lord—and you have an illustration of the blessedness which follows a religious life.”
