Deuteronomy 23:1-25

1 He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the LORD.

2 A bastard shall not enter into the congregation of the LORD; even to his tenth generation shall he not enter into the congregation of the LORD.

3 An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD for ever:

4 Because they met you not with bread and with water in the way, when ye came forth out of Egypt; and because they hired against thee Balaam the son of Beor of Pethor of Mesopotamia, to curse thee

5 Nevertheless the LORD thy God would not hearken unto Balaam; but the LORD thy God turned the curse into a blessing unto thee, because the LORD thy God loved thee.

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

7 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.

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

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

10 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:

11 But it shall be, when evening cometh on, he shall wash himself with water: and when the sun is down, he shall come into the camp again.

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

13 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:

14 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 uncleanb thing in thee, and turn away from thee.

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

16 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.

17 There shall be no whorec of the daughters of Israel, nor a sodomite of the sons of Israel.

18 Thou shalt not bring the hire of a whore, or the price of a dog, into the house of the LORD thy God for any vow: for even both these are abomination unto the LORD thy God.

19 Thou shalt not lend upon usury to thy brother; usury of money, usury of victuals, usury of any thing that is lent upon usury

20 Unto a stranger thou mayest lend upon usury; but unto thy brother thou shalt not lend upon usury: that the LORD thy God may bless thee in all that thou settest thine hand to in the land whither thou goest to possess it.

21 When thou shalt vow a vow unto the LORD thy God, thou shalt not slack to pay it: for the LORD thy God will surely require it of thee; and it would be sin in thee

22 But if thou shalt forbear to vow, it shall be no sin in thee.

23 That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.

24 When thou comest into thy neighbour's vineyard, then thou mayest eat grapes thy fill at thine own pleasure; but thou shalt not put any in thy vessel.

25 When thou comest into the standing corn of thy neighbour, then thou mayest pluck the ears with thine hand; but thou shalt not move a sickle unto thy neighbour's standing corn.

In chapter twenty-three, we find those that were restricted from coming into the temple. Eunuchs were forbidden in the temple.

An Ammonite or Moabite was forbidden unto the tenth generation, for their failure to help the children of Israel during their wilderness experiences, and because they hired Balaam to curse them. And you're not to seek their peace or their prosperity. However an Edomite; being the descendents of Esau: and the Egyptians; because you were a stranger in their land. They may be brought into the congregation of the LORD in their third generation (Deuteronomy 23:3-8).

Now, there are certain rules of cleanliness and sanitation that are given to them here that are very practical and I don't need to read them or rehearse them for you.
And in verse fifteen,

Thou shalt not deliver unto his master the servant which is escaped from his master to you. There shall be no whores of the daughters of Israel, nor a sodomite among the sons of Israel. You're not to bring the hire of a whore, or the price of a dog, into the house of the LORD for any vow that you want to make unto God: for these are an abomination unto the LORD thy God. You're not to lend upon usury to your brother; that is of money, or victuals, or of anything that is lent upon usury: to a stranger you may lend with usury; but unto your brother you shall not lend upon usury: that the LORD thy God may bless thee in all that you set your hand to do in the land for wherever you goeth. And when you vow a vow unto the LORD thy God, thou shalt not slack to pay it: for the LORD thy God will surely require it; and if you do not pay your vow it will be a sin to you. That which has gone out of your lips, you shall keep and perform it; the freewill offering, according as you have vowed unto the LORD, and you promised with your mouth. Now, when you come into your neighbor's vineyard, you may eat all of the grapes you want; but you're not to put any in a container to carry out of the vineyard (Deuteronomy 23:15-24).

In other words, you go into a field, you're allowed to eat all of the grapes that you can hold while you're in the field, but you can't carry them out of the field except in your stomach.

When you come into the standing corn of your neighbor, you may pluck the ears with thine hand; but thou shalt not move a sickle to your neighbor's (Deuteronomy 23:25)

In other words, what you can carry out with your hand, but you're not to take a sickle to his standing corn.
