Devarim (Deuteronomy): Ki Teitzei > Ch 23
An Ammonite or Moabite shall not enter the assembly of the Lord
An Ammonite or Moabite shall not enter the assembly of the Lord; even the tenth generation shall never enter the assembly of the Lord. Because they did not greet you with bread and water on the way, when you left Egypt, and because he [the people of Moab] hired Balaam the son of Beor from Pethor in Aram Naharaim against you, to curse you. But the Lord, your G-d, did not want to listen to Balaam. So the Lord, your G-d, transformed the curse into a blessing for you, because the Lord, your G-d, loves you. You shall not ever seek out their welfare or their good, all your days.
You shall not despise Edomites and Egyptians
You shall not despise an Edomite, for he is your brother. You shall not despise an Egyptian, for you were a sojourner in his land. Children who are born to them [in] the third generation may enter the assembly of the Lord.
When a camp goes against enemies, use restrooms and keep the camp clean and holy
When a camp goes out against your enemies, you shall beware of everything evil. If there is among you a man who is unclean because of a nocturnal emission, he shall go outside the camp. He shall not come within the camp. And it shall be, towards evening, he shall bathe in water, and when the sun sets, he may come within the camp. And you shall have a designated place outside the camp, so that you can go out there [to use it as a privy]. And you shall keep a stake in addition to your weapons; and it shall be, when you sit down outside [to relieve yourself], you shall dig with it, and you shall return and cover your excrement. For the Lord, your G-d, goes along in the midst of your camp, to rescue you and to deliver your enemies before you. [Therefore,] your camp shall be holy, so that He should not see anything unseemly among you and would turn away from you.
Don’t return a runaway slave, and don’t oppress him
You shall not deliver a slave to his master if he seeks refuge with you from his master. [Rather,] he shall [be allowed to] reside among you, wherever he chooses within any of your cities, where it is good for him. You shall not oppress him.
You shall not pay interest to your brother
You shall not give interest to your brother, [whether it be] interest on money, interest on food or interest on any [other] item for which interest is [normally] taken. You may [however,] give interest to a gentile, but to your brother you shall not give interest, in order that the Lord, your G-d, shall bless you in every one of your endeavors on the land to which you are coming to possess
When you make a vow to the Lord, your G-d, you shall not delay in paying it, for the Lord, your G-d, will demand it of you, and it will be [counted as] a sin for you.
But if you shall refrain from making vows, you will have no sin. Observe and do what is emitted from your lips just as you have pledged to the Lord, your G-d, as a donation, which you have spoken with your mouth.
You may eat grapes from your neighbor’s vineyard but don’t collect any in a vessel
When you enter your neighbor's vineyard, you may eat as many grapes as you desire, until you are sated, but you shall not put [any] into your vessel. When you enter your neighbor's standing grain, you may pick the ears with your hand, but you shall not lift a sickle upon your neighbor's standing grain.
