Genesis 24:13-14

13Here I am, standing beside the spring, and the daughters of the townspeople are coming out to draw water. 14Now may it happen that the girl to whom I say, ‘Please let down your jar that I may drink,’ and who responds, ‘Drink, and I will water your camels as well’—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.”
