1 Samuel 30:11

for I was hungry, and ye gave me to eat: I was thirsty, and ye gave me to drink: I was a stranger, and ye received me hospitably:

Which then of these three do you suppose to be the neighbour of him who fell into the robbers' hands?

If therefore thine enemy hunger, give him food; if he thirst, give him drink: for so doing, thou shalt heap up coals of fire on his head.

and if I send them away fasting to their houses, they will faint on the road; for many of them came from a great distance.
