John Calvin Commentary Genesis 24:59

"And they sent away Rebekah their sister, and her nurse, and Abraham`s servant, and his men." — Genesis 24:59 (ASV)

And they sent away Rebekah. Moses first relates that Rebekah was honorably dismissed, because her nurse was given to her. Moreover, I do not doubt that they had domestic nurses, who were their female servants; not that mothers entirely neglected that duty, but that they committed the care of education to one particular maid.

Therefore, those who assisted mothers with subsidiary service were called nurses. Moses afterwards adds that Rebekah’s relatives blessed her (Genesis 24:60), by which expression he means that they prayed that her life might be happy. We know that it was a solemn custom in all ages and among all people, to accompany marriages with all good wishes.

And although posterity has greatly degenerated from the pure and genuine method of celebrating marriages used by the fathers, it is still God’s will that some public testimony should stand forth, by which people may be admonished that no marriages are lawful unless they are rightly consecrated. Now, the particular form of benediction described here was probably in common use, because nature dictates that the propagation of offspring is the primary purpose of marriage.

Under the notion of victory (Genesis 24:60), a prosperous state of life is included. The Lord, however, directed their tongues to utter a prophecy of which they themselves were unaware. To possess the gates of enemies means to obtain dominion over them, because judgment was administered in the gates, and the city’s fortifications were placed there.
