'Zealous' in the Bible

"I am a Jew, born in Tarsus in Cilicia, but brought up in this city, educated with strictness under Gamaliel according to the law of our ancestors, and was zealous for God just as all of you are today.

For I can testify that they are zealous for God, but their zeal is not in line with the truth.

I was advancing in Judaism beyond many of my contemporaries in my nation, and was extremely zealous for the traditions of my ancestors.
