John Gill 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 their sister Not in a pet or angry humour, but with good will; they agreed she should go, and took their leave in a very honourable and affectionate manner. This is to be understood of her brother Laban, and of other brethren and sisters she might have; though by the connection of the words with the preceding, they seem to design her brother and mother, who spoke last; and probably all her relations are meant, who call her their sister, because so nearly related to them.

and her nurse: who had been her nurse in former times, as Aben Ezra observes, in her infancy, for whom she had a particular affection, as is often the case; her name was Deborah, as appears from (Genesis 35:8).

and Abraham's servant, and his men; who were dismissed in an handsome manner by the family.
