John Calvin Commentary Genesis 24:26

"And the man bowed his head, and worshipped Jehovah." — Genesis 24:26 (ASV)

And the man bowed down his head. When Abraham's servant hears that he had come upon the daughter of Bethel, he is more and more elated with hope. Yet he does not exult, as profane men are accustomed to do, as if the occurrence were fortuitous; but he gives thanks to God, regarding it as the result of Providence that he had been so opportunely led straight to the place he had wished. He does not, therefore, boast of his good fortune; but he declares that God had dealt kindly and faithfully with Abraham; or, in other words, that for His own mercy’s sake, God had been faithful in fulfilling His promises. It is true that the same form of speech is applied to the people present, just as it follows soon after in the same chapter (Genesis 24:49):

If you will deal kindly and truly with my master, tell me.

This language, however, is peculiarly suitable to the character of God, both because He gratuitously confers favors upon men and is especially inclined to beneficence, and also because, by never frustrating their hope, He proves Himself to be faithful and true. This thanksgiving, therefore, teaches us always to keep the providence of God before our eyes, so that we may ascribe to Him whatever happens prosperously to us.
