Didache 12

But let every one that cometh in the Lord's name be received, but afterward ye shall test and know him; for ye shall have understanding, right and left. If he who comes is a traveller, help him a much as ye can; but he shall not remain with you, unless for two or three days, if there be necessity. But if he will take up his abode among you, being an artisan, let him work and so eat; but if he have no trade, provide, according to your understanding, that no idler live with you as a Christian. But if he will not act accord- ing to this, he is one who makes gain out of Christ; be- ware of such.
