Dickson on Psalm 8:3-4:

3. When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained.4. What is man, that thou art mindful of him? and the son of man, that thou visitest him?

From his admiration in God’s respect, and love to man above all other creatures, learn, 1. The weakness and unworthiness of man, considered both in himself, and compared with his glorious creatures made for his use, commend the bounty of God to man, and make it a matter of great admiration. For when the prophet considers the glorious heavens, &c. he asks what is man, &c. 2. Man of all the creatures is most esteemed and taken care of by God; for he is mindful of man, and daily visits him.
