All thy wants lie upon me - Here was genuine hospitality: "Keep your bread and wine for yourselves, and your straw and provender for your asses; you may need them before you finish your journey; I will supply all your wants for this night, therefore do not lodge in the street."

And the old man said, peace be with you,.... All happiness attend thee, particularly ease and tranquillity of mind, let nothing disturb or distress thee:
howsoever, let all thy wants lie upon me; signifying, that if he had neither bread nor wine for himself, his wife, and his servant, nor any litter nor provender for his asses, he was welcome to all from him; and whatever his wants were, he would supply them, which was nobly and generously said:
only lodge not in the street: that I cannot bear to think of, as if he should say; for a stranger, an Israelite, one of my own country, a good man, a Levite going to the house of God, to take up a lodging in the streets, let it not be said.

only lodge not in the street--As this is no rare or singular circumstance in the East, the probability is that the old man's earnest dissuasive from such a procedure arose from his acquaintance with the infamous practices of the place.

The old man replied, "Peace to thee," assuring him of a welcome by this style of greeting; "only all thy wants upon me," i.e., let me provide for them. Thus the friendly host declined the offer made by his guest to provide for himself. "Only do not pass the night in the market-place."

Let all, &c. - It matters not whether thou wantest nothing or everything, I will take care to supply all thy wants.
