'Zealous' in the Bible

And [when] they heard [this], they began to glorify God. And they said to him, "You see, brother, how many ten thousands there are among the Jews who have believed, and they are all zealous adherents of the law.

"I am a Jewish man born in Tarsus in Cilicia, but brought up in this city at the feet of Gamaliel, educated according to the exactness of the law received from our fathers, being zealous for God, just as all [of] you are today.
