Deuteronomy 23:11 (KJV)

Thou shalt not seek their peace nor their prosperity all thy days for ever.

Thou shalt not abhor an Edomite; for he is thy brother: thou shalt not abhor an Egyptian; because thou wast a stranger in his land.

The children that are begotten of them shall enter into the congregation of the LORD in their third generation.

When the host goeth forth against thine enemies, then keep thee from every wicked thing.

If there be among you any man, that is not clean by reason of uncleanness that chanceth him by night, then shall he go abroad out of the camp, he shall not come within the camp:

Thou shalt have a place also without the camp, whither thou shalt go forth abroad:

And thou shalt have a paddle upon thy weapon; and it shall be, when thou wilt ease thyself abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:

For the LORD thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; therefore shall thy camp be holy: that he see no unclean thing in thee, and turn away from thee.

Thou shalt not deliver unto his master the servant which is escaped from his master unto thee:

He shall dwell with thee, even among you, in that place which he shall choose in one of thy gates, where it liketh him best: thou shalt not oppress him.
