I am in no way attempting to attack or defame the Lord, nor am I attempting to advocate for violent actions against sinners(For all have sinned, and come short of the glory of God). My goal with this discussion is to better understand and to better know the UNCHANGING God of the Bible.
These are real people too. They names and parents. Real people who existed and loved by God yet violently slain for sin. God rewarded His people for slaying them, with a special blessing for Phinehas.
Numbers 25 And Israel abode in [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse]tim, and the people began to commit whoredom with the daughters of Moab.
2 And they called the people unto the sacrifices of their gods: and the people did eat, and bowed down to their gods.
3 And Israel joined himself unto Baalpeor: and the anger of the Lord was kindled against Israel.
4 And the Lord said unto Moses, Take all the heads of the people, and hang them up before the Lord against the sun, that
the fierce anger of the Lord may be turned away from Israel.
5 And Moses said unto the judges of Israel, Slay ye every one his men that were joined unto Baalpeor.
6 And, behold, one of the children of Israel came and brought unto his brethren a Midianitish woman in the sight of Moses, and in the sight of all the congregation of the children of Israel, who were weeping before the door of the tabernacle of the congregation.
7 And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from among the congregation, and took a javelin in his hand;
8 And he went after the man of Israel into the tent, and thrust both of them through, the man of Israel, and the woman through her belly. So the plague was stayed from the children of Israel.
9 And those that died in the plague were twenty and four thousand.
10 And the Lord spake unto Moses, saying,
11 Phinehas, the son of Eleazar, the son of Aaron the priest, hath turned my wrath away from the children of Israel, while he was zealous for my sake among them, that I consumed not the children of Israel in my jealousy.
12 Wherefore say, Behold, I give unto him my covenant of peace:
13 And he shall have it, and his seed after him, even the covenant of an everlasting priesthood; because he was zealous for his God, and made an atonement for the children of Israel.
14 Now the name of the Israelite that was slain, even that was slain with the Midianitish woman, was Zimri, the son of Salu, a prince of a chief house among the Simeonites.
15 And the name of the Midianitish woman that was slain was Cozbi, the daughter of Zur; he was head over a people, and of a chief house in Midian.
16 And the Lord spake unto Moses, saying,
17 Vex the Midianites, and smite them:
18 For they vex you with their wiles, wherewith they have beguiled you in the matter of Peor, and in the matter of Cozbi, the daughter of a prince of Midian, their sister, which was slain in the day of the plague for Peor's sake.
How does this show the Love of the unchanging God of the Bible? We are not talking about God destroying these people Himself as in the Flood or Sodom and Gomorrah. In this case, He is instructing His people to destroy these wicked people.
Below I have included a similar call to purge by the Apostle Paul which calls on the congregation at Corinth "To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus."
1 Corinthians 5
It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.
2 And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you.
3 For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed,
4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ,
5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
9 I wrote unto you in an epistle not to company with fornicators:
10 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.
11 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 idolator, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
12 For what have I to do to judge them also that are without? do not ye judge them that are within?
13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.
