Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
All Commentaries on Genesis 18:4 Go To Genesis 18
Caesarius of Arles
AD 542
Moreover he adds, as though speaking to the men, “I will bring water, that you may wash your feet.” Learn from blessed Abraham, brothers, to receive strangers gladly and to wash their feet with humility and piety. Wash, I repeat, the feet of pious strangers, lest there remain in them some dust that they will be able to shake off of their feet to your judgment. In the Gospel we read, “Whoever does not receive you— go forth and shake off the dust from your feet. Amen, I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment than for that town.” Abraham foresaw this in spirit and for this reason wanted to anticipate it by washing their feet, lest perchance any dust remain that might be kept and shaken off on judgment day as an evidence of unbelief. Therefore the wise Abraham says, “I will bring water, that you may wash your feet.” Carefully listen to this, brothers, if you are unwilling to exercise hospitality and to receive even your enemy as a guest. Behold, while blessed Abraham welcomed those men warmly, he merited to receive God in consideration of his hospitality. Christ further confirmed this in the Gospel when he said, “I was a stranger, and you took me in.” Therefore do not despise strangers, lest perhaps he himself be the one you have rejected.
