Didache

But be thou meek, since the meek shall inherit the earth. Be long-suffering and pitiful and guileless and gentle and good and always trembling at the words which thou hast heard. Thou shalt not exalt thyself, nor give over-confidence to thy soul. Thy soul shall not be joined with lofty ones, but with just and lowly ones shall it have its intercourse. The workings that befall thee receive as good, knowing that apart from God nothing cometh to pass.

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