Deuteronomy

They had also paid Balaam to work against the Israelites.

Deuteronomy 23:3-4
"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: 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."

The ban on entering the congregation of the Lord does not mean that they were not allowed to convert to Judaism, but that intermarriage was not permitted. This only applied to males, as King David's ancestor, Ruth, was a Moabite

Deuteronomy 5:22
"These words the Lord spake unto all your assembly in the mount out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. And he wrote them in two tables of stone, and delivered them unto me."

Here are the Ten Commandments once more:

Deuteronomy 5:7-21
"Thou shalt have none other gods before me.
Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth: thou shalt not bow down thyself unto them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me, and shewing mercy unto thousands of them that love me and keep my commandments.
Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his name in vain.
Keep the sabbath day to sanctify it, as the Lord thy God hath commanded thee. Six days thou shalt labour, and do all thy work: but the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy manservant and thy maidservant may rest as well as thou. And remember that thou wast a servant in the land of Egypt, and that the Lord thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the Lord thy God commanded thee to keep the sabbath day.
Honour thy father and thy mother, as the Lord thy God hath commanded thee; that thy days may be prolonged, and that it may go well with thee, in the land which the Lord thy God giveth thee.
Thou shalt not kill.
Neither shalt thou commit adultery.
Neither shalt thou steal.
Neither shalt thou bear false witness against thy neighbour.
Neither shalt thou desire thy neighbour’s wife, neither shalt thou covet thy neighbour’s house, his field, or his manservant, or his maidservant, his ox, or his ass, or any thing that is thy neighbour’s"

Deuteronomy 28:64
"And the Lord shall scatter thee among all people, from the one end of the earth even unto the other; and there thou shalt serve other gods, which neither thou nor thy fathers have known, even wood and stone."

But that is not all. God said he would curse the Israelites' cities and fields, let their enemies destroy them and visit them with plagues if they disobeyed His commandments

The Song of Moses tells of God's faithfulness to His chosen people, His threat to destroy them if they disobey Him and how He will never desert them. It ends with the verse:

Deuteronomy 32:43
Rejoice, O ye nations, with his people: for he will avenge the blood of his servants, and will render vengeance to his adversaries, and will be merciful unto his land, and to his people

Deuteronomy 1:5-6
"on this side Jordan, in the land of Moab, began Moses to declare this law, saying, The Lord our God spake unto us in Horeb, saying, Ye have dwelt long enough in this mount."

In this first speech Moses recounts the adventures of the Israelites since they left Mount Sinai almost 40 years before, up until they came to Moab

Deuteronomy 30:3-5
"that then the Lord thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the Lord thy God hath scattered thee. If any of thine be driven out unto the outmost parts of heaven, from thence will the Lord thy God gather thee, and from thence will he fetch thee: and the Lord thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers."

This promise was granted in the 20th century when the Jews returned to their homeland and the nation of Israel was refounded

Deuteronomy 34:5-6
"So Moses the servant of the Lord died there in the land of Moab, according to the word of the Lord. And he buried him in a valley in the land of Moab, over against Beth-peor: but no man knoweth of his sepulchre unto this day."

Moses is the only person in the Bible to have been buried by God

Deuteronomy 34:7
"And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated."

Moses was the greatest prophet ever to have lived.

Deuteronomy 34:10-12
"And there arose not a prophet since in Israel like unto Moses, whom the Lord knew face to face, in all the signs and the wonders, which the Lord sent him to do in the land of Egypt to Pharaoh, and to all his servants, and to all his land, and in all that mighty hand, and in all the great terror which Moses shewed in the sight of all Israel"

Deuteronomy 6:4-5
"Hear, O Israel: The Lord our God is one Lord: and thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might."

Jesus Christ Himself said that this was the greatest of all commandments in the Book of Mark 12: 28-34

God promised many blessings including to bless their cities and fields and to defeat their enemies. All this depended on the Israelites obeying God's laws.

Deuteronomy 28:13-14
"And the Lord shall make thee the head, and not the tail; and thou shalt be above only, and thou shalt not be beneath; if that thou hearken unto the commandments of the Lord thy God, which I command thee this day, to observe and to do them: and thou shalt not go aside from any of the words which I command thee this day, to the right hand, or to the left, to go after other gods to serve them"
