Genesis 24:13-14

13I am standing here at the spring where the daughters of the men of the town are coming out to draw water.

14Let the girl to whom I say, ‘Please lower your water jug so that I may drink,’ and who responds, ‘Drink, and I’ll water your camels also’ — let her be the one you have appointed for your servant Isaac. By this I will know that you have shown kindness to my master.”
