Musar su Esodo 32:26

One who does not perpetuate a dispute against those who stand on a path that is not good, and those that haul in iniquity, is surely punished for their transgressions in all their sins (of the actual sinners); and [also] transgresses a negative commandment - as it is stated (Leviticus 19:17), “and not bear sin because of him..” And it is stated (Hosea 10:9) “You have sinned more, O Israel, than in the days of Gibeah; there they stand; shall they not be overtaken [as] at Gibeah by a war upon scoundrels?” Its explanation is [that] if that generation (of Hosea) was standing there, they would not have overtaken those in Gibeah in war, to destroy the evil, as that generation had overcome [the evildoers of that time] in war. The understanding of “there they stand” is, if they stood there. And likewise “and leave his father” (Genesis 44:22) is, if he left. [This is] meaning to say, that their sin was of the type of sin of Gibeah. However [the earlier generation] was better than these, since they gathered and stood with their lives to destroy the evil. And it is stated (Judges 5:23), “‘Curse Meroz,’ said the angel of the Lord; ‘Bitterly curse its inhabitants, because they came not to the aid of the Lord, to the aid of the Lord among the warriors.” And it is stated (Deuteronomy 1:17), “do not fear in front of a man.” And anyone who is for God, may He be blessed, should give over his life for the sanctification of God, as it is stated (Exodus 32:26), “‘Whoever is for the Lord, come to me’; and all the Levites gathered to him.” And it is [also] stated (Numbers 25:7), “And Phinheas saw, etc. and he took a spear in his hand.” And it is an obligation on all that fear [God] - even if he is one that loves pureness of heart - to arouse zealotry when he sees that behold, the officers and the prefects are in trespass, as it is stated (Ezra 9:2), “and it was the hand of the officers and prefects who were in this trespass first.”

Moses was jealous of the Egyptian, as it is said, "And he smote the Egyptian" (Exod. 2:12). And so we find in the case of Elijah, when he said, "I have been very jealous for the Lord, the God of hosts, for the children of Israel have forsaken Thy covenant" (I Kings 19:10). And so is it said, "In that he was very jealous for My sake among them" (Num. 25:11), and the Lord, may He be Blessed, gave him his reward for this as it is said : "Behold, I give unto him My covenant of peace!" (Num. 25:12). And it is said, "… Ye shall not be afraid of any man …" (Deut. 1:17). Now he who reveres the Lord, may He be Blessed, will gladly offer his life for the sanctification of God's name. As it is said, "Whoso is on the Lord's side, let him come unto me. And all the Levites rallied to him" (Exod. 32:26), and it is further said, "And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from the midst of the congregation, and took a spear in his hand" (Num. 25:7).
