Adam Clarke's Bible Commentary Verse 4. His breath goeth forth ] His existence depends merely, under God, on the air he breathes. When he ceases to respire he ceases to live; his body from that moment begins to claim its affinity to the earth; and all his thoughts, purposes, and projects, whether good or evil, come to nought and perish. He, then, who has no other dependence, must necessarily be miserable.
Matthew Henry Commentary
Verses 1-4 - If it is our delight to praise the Lord while we live, we shal certainly praise him to all eternity. With this glorious prospect before us, how low do worldly pursuits seem! There is a Son of man i whom there is help, even him who is also the Son of God, who will no fail those that trust in him. But all other sons of men are like the man from whom they sprung, who, being in honour, did not abide. God ha given the earth to the children of men, but there is great strivin about it. Yet, after a while, no part of the earth will be their own except that in which their dead bodies are laid. And when man return to his earth, in that very day all his plans and designs vanish and ar gone: what then comes of expectations from him?
