Who was Phinehas in the Bible

Phinehas was regarded as the Protector of Orthodox Faith, the actions he took on many occasions saved the Israelites from the wrath of God. He was the son of Eleazar I.e the grandson of Aaron.

“Phinehas the son of Eleazar, son of Aaron the priest, has turned back my wrath from the people of Israel, in that he was jealous with my jealousy among them, so that I did not consume the people of Israel in my jealousy.” NUMBERS 25:11 ESV

Phinehas did not shy away from confrontation. When the people of Israel faced the temptation to stray from the strict, orthodox teachings of God’s law, Phinehas took the crucial steps to correct the error. Having seen (or heard about) the steps God took to quell the unholy acts of Korah, Abihu, and Nadab, Phinehas knew the necessity of taking drastic action to bring the people back in line.
On one occasion, Hebrew men began to stray from God by indulging in idolatry and sexual sins with women from Midian. One particularly brazen man paraded a Midianite woman through the people of Israel and into his tent. The Bible records that “When Phinehas saw this, he left the assembly, took a spear in his hand and followed the Israelite into the tent. He drove the spear through both of them – through the Israelite and into the woman’s body” (Numbers 25:7–8). As a result, the plague that God had brought against the people was stopped.
On another occasion, certain tribes were suspected of building their own altars in competition to the one that the tabernacle housed. Since God had ordained only one altar, Phinehas explored and resolved the situation (Joshua 22). On yet another occasion, the tribe of Benjamin committed a horrific rape and murder (Judges 20). When the Benjamites remained unrepentant for their actions, Phinehas led the ensuing fight against his own countrymen. Phinehas’s courage and moral strength made him one of the best known defenders of God’s law.
There is a lesson to be learned from Phinehas. While Christians may disagree about finer points of doctrine or worship practices, they cannot make exceptions when it comes to the core message of the gospel. When Phinehas saw the people leave the faith and stray into idolatry, he boldly confronted them. While some lines of doctrinal differences may not be worth splitting hairs over, others are worth
defending to the end.
