Didache

But whosoever shall say in a spirit ‘Give me money, or something else,’ you shall not listen to him; but if he tell you to give on behalf of others in want, let none judge him.

Let everyone who comes in the Name of the[*](Travelling Christians) Lord be received; but when you have tested him you shall know him, for you shall have understanding of true and false.[*](Literally, right and left understanding.)

If he who comes is a traveller, help him as much as you can, but he shall not remain with you more than two days, or, if need be, three.

And if he wishes to settle among you and has a craft, let him work for his bread.
