John Calvin Commentary Genesis 24:52

"And it came to pass, that, when Abraham`s servant heard their words, he bowed himself down to the earth unto Jehovah." — Genesis 24:52 (ASV)

He worshipped. Moses again repeats that Abraham’s servant gave thanks to God; and it is not without reason that he so often stresses this religious duty. For since God requires nothing greater from us, neglecting it betrays the most shameful laziness. The acknowledgment of God’s kindness is a sacrifice of sweet-smelling savor; indeed, it is a more acceptable service than all sacrifices. God is continually heaping innumerable benefits upon people. Their ingratitude, therefore, is intolerable if they fail to celebrate those benefits.
