Genesis

Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:

And the man came into the house: and he ungirded his camels, and gave straw and provender for the camels, and water to wash his feet, and the men’s feet that were with him.

And he said, Behold now, my lords, turn in, I pray you, into your servant’s house, and tarry all night, and wash your feet, and ye shall rise up early, and go on your ways. And they said, Nay; but we will abide in the street all night.

So he brought him into his house, and gave provender unto the asses: and they washed their feet, and did eat and drink.
