What does Genesis 24:25 mean?

Abraham's servant has already seen a sign from God, in response to his prayer. After being sent to find a wife for Abraham's son, Isaac, among Abraham's family in Mesopotamia, the servant prays. In response to this prayer, Rebekah appears and fulfills the sign (Genesis 24:12–19). The servant then gives her lavish gifts, and asks about her family and possibly staying overnight with her father (Genesis 24:22–24). Her answer delights the servant—she is, indeed, part of the family Abraham wanted this man to contact.

In addition to her unknowing revelation that she is the granddaughter of Abraham's own brother, generous Rebekah adds that her family does indeed have room for this traveling stranger to spend the night. She even thinks of the camels, mentioning they have both straw and fodder enough to accommodate the beasts. Given the room for both men and animals, Rebekah's family apparently has some amount of wealth.

She stops short of offering to allow the company to stay with them. As a young women in her father's household, that would not be her role. Rather, Rebekah's answer indicates that her family can accommodate the servant and his entourage, not that they necessarily will.
