Didache

But let every one that comes in the name of the Lord be received, and afterward you shall prove and know him; for you shall have understanding right and left. If he who comes is a wayfarer, assist him as far as you are able; but he shall not remain with you, except for two or three days, if need be. But if he wills to abide with you, being an artisan, let him work and eat; 2 Thessalonians 3:10 but if he has no trade, according to your understanding see to it that, as a Christian, he shall not live with you idle. But if he wills not to do, he is a Christ-monger. Watch that you keep aloof from such.
