Commanded not to covet
Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbour's. (Exodus 20:17)
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 5:21)
The graven images of their gods shall ye burn with fire: thou shalt not desire the silver or gold that is on them, nor take it unto thee, lest thou be snared therein: for it is an abomination to the LORD thy God. (Deuteronomy 7:25)
Punishment threatened for coveting
And ye, in any wise keep yourselves from the accursed thing, lest ye make yourselves accursed, when ye take of the accursed thing, and make the camp of Israel a curse, and trouble it. (Joshua 6:18)
Woe to them that devise iniquity, and work evil upon their beds! when the morning is light, they practise it, because it is in the power of their hand. And they covet fields, and seize them; and houses, and take them away: so they oppress a man and his house, even a man and his heritage. Therefore thus saith the LORD; Behold, against this family do I devise an evil, from which ye shall not remove your necks; neither shall ye go haughtily: for this is an evil time. (Micah 2:1-3)
Example of punishment for coveting
...1 Israel has sinned, and they have also transgressed My covenant which I commanded them. For they have even taken some of the [a]accursed things, and have both stolen and deceived; and they have also put it among their own stuff. Therefore the children of Israel could not stand before their enemies, but turned their backs before their enemies, because they have become doomed to destruction. Neither will I be with you anymore, unless you destroy the accursed from among you. Get up, sanctify[b] the people, and say, ‘Sanctify yourselves for tomorrow, because thus says the Lord God of Israel: “There is an accursed thing in your midst, O Israel; you cannot stand before your enemies until you take away the accursed thing from among you.” 14 In the morning therefore you shall be brought according to your tribes. And it shall be that the tribe which the Lord takes shall come according to families; and the family which the Lord takes shall come by households; and the household which the Lord takes shall come man by man. 15 Then it shall be that he who is taken with the accursed thing shall be burned with fire, he and all that he has, because he has transgressed[c] the covenant of the Lord, and because he has done a disgraceful thing in Israel.’ ”So Joshua rose early in the morning and brought Israel by their tribes, and the tribe of Judah was taken. He brought the clan of Judah, and he took the family of the Zarhites; and he brought the family of the Zarhites man by man, and Zabdi was taken. Then he brought his household man by man, and Achan the son of Carmi, the son of Zabdi, the son of Zerah, of the tribe of Judah, was taken. Now Joshua said to Achan, “My son, I beg you, give glory to the Lord God of Israel, and make confession to Him, and tell me now what you have done; do not hide it from me.”And Achan answered Joshua and said, “Indeed I have sinned against the Lord God of Israel, and this is what I have done: When I saw among the spoils a beautiful Babylonian garment, two hundred shekels of silver, and a wedge of gold weighing fifty shekels, I [d]coveted them and took them. And there they are, hidden in the earth in the midst of my tent, with the silver under it.”So Joshua sent messengers, and they ran to the tent; and there it was, hidden in his tent, with the silver under it. And they took them from the midst of the tent, brought them to Joshua and to all the children of Israel, and laid them out before the Lord. Then Joshua, and all Israel with him, took Achan the son of Zerah, the silver, the garment, the wedge of gold, his sons, his daughters, his oxen, his donkeys, his sheep, his tent, and all that he had, and they brought them to the Valley of Achor. And Joshua said, “Why have you troubled us? The Lord will trouble you this day.” So all Israel stoned him with stones; and they burned them with fire after they had stoned them with stones. (Joshua 7:11-25)
Examples of coveting given to instruct us
Now these things were our examples, to the intent we should not lust after evil things, as they also lusted. (1 Corinthians 10:6)
The covetous shall not inherit the Kingdom of God
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. (1 Corinthians 6:9-10)
Covetous person is an idolater
But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints; (Ephesians 5:3)
For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. (Ephesians 5:5)
Do not associate with a covetous believer
I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. (1 Corinthians 5:9-11)
Example of godly person not coveting
I have coveted no man's silver, or gold, or apparel. (Acts 20:33)
God can control coveting
Thrice in the year shall all your menchildren appear before the Lord GOD, the God of Israel. For I will cast out the nations before thee, and enlarge thy borders: neither shall any man desire thy land, when thou shalt go up to appear before the LORD thy God thrice in the year. (Exodus 34:23-24)
Coveting used as illustration of the function of the law
What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet. But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead. (Romans 7:7-8)
