'Zealousness' in the Bible

"Eleazar's son Phinehas, grandson of Aaron the priest, has turned my wrath away from Israel. Because his zealousness reflected my own zeal for them, I didn't consume Israel in my jealousy.

""Because this is what the Lord GOD says: "Motivated by my burning zealousness, I have spoken against the rest of the surrounding nations, including Edom, who confiscated my land, taking possession of it with joyful enthusiasm and with animal-like malice, in order to plunder Israel's pastures.'
