John Calvin on Genesis 24:52-53

52. He worshipped. Moses again repeats that Abraham’s servant gave thanks to God; and it is not without reason that he so often inculcates this religious duty; because, since God requires nothing greater from us, the neglect of it betrays the most shameful indolence. The acknowledgment of God’s kindness is a sacrifice of sweet-smelling savor; yea, it is a more acceptable service than all sacrifices. God is continually heaping innumerable benefits upon men. Their ingratitude, therefore, is intolerable, if they fail to exercise themselves in celebrating those benefits.
