Genesis 24:18-20

‘And she said, “Drink, sir.” And she hastily let down her pitcher on her hand and gave him a drink. And when she had finished giving him a drink she said, “I will also draw for your camels until they have had enough to drink.” And she quickly emptied her pitcher into the trough and ran again to the well to draw, and drew for all his camels.'

The well is clearly a large, deep hole in the ground with steps leading down to the spring. It is also clear that there was a trough by the well for the feeding of animals, and without hesitation Rebekah fulfils the steward's requirements in accordance with the covenant he had made with Yahweh. Ten camels would take a lot of satisfying which is a testimony to the goodness of her heart. However she was also no doubt impressed with his rich appearance.
