Phinehas has turned my anger away from the Isrealites by being as zealous among them as I was - Numbers 25:10
Phinehas had seen the immorality going on around him and could not stand idly by and allow his people tp defile themselves
Neither could he allow God judgement to continue without trying to bring it to an end
His last straw momenet was when he witnessed his Hebrew brother shamelessly taking a Midianite into his tent
Phinehas' zeal kicked in and passionately executed the man
From then on, he showed his willingness to take a stand and the people of Israel were spared and decendants received God's blessings - Numbers 25:12-13
When you are enthusiastic about your relationship with God, you are bound to affect the people around you
