Genesis 24:19

And when she had done giving him drink,.... Whatever he pleased to have:

she said, I will draw [water] for thy camels also, until they have done drinking; she proposed to go back to the well, and did, and fill her pitcher, and repeat it as often as was necessary, until the camels had enough; and this now was the sign or token the servant had desired might be, by which he would know who was the person intended for the wife of his master's son; and this was granted him, which shows that it was not a rash and ill thing which he asked, but what was agreeable to the will of God, and to which he was directed by an impulse of his.
