Genesis 24:20

“And she hasted and emptied her pitcher into the trough, etc.] The place out of which cattle drank water, being put there for that purpose, which was of wood or of stones made hollow; into this Rebekah poured out what was left in her pitcher after the servant had drank: and ran again to the well to draw [water]; and which must be repeated several times to have enough for all the camels, for it follows: and drew for all his camels; and there were ten of them; and these, being thirsty after so long a journey, required a great deal of water to satisfy them; therefore Rebekah must take a vast deal of pains and labour to draw water for them all until they had enough.”
