In the third aliyah Eliezer arrives at Avrohom's homeland and waits outside the city by the well of water. Here he prays to G-d that his mission of finding a wife for Yitzchak should be quickly successful. He prays that he will ask a young lady for a drink of water, and when she answers, she will say "of course, and I'll also give your camels water to drink." But before he finishes speaking, a young lady approaches and he asks for a drink, and she says "of course" and offers also to feed his camels. And naturally, she turns out to be from the correct family, too.
