When they heard this, they praised God. Then they said to him, "You see, brother, how many thousands of Jews there are who have believed, and they are all ardent observers of the law.

“I am a Jew, born in Tarsus of Cilicia, but brought up in this city, educated at the feet of Gamaliel according to the strictness of the law of our fathers, being ardent and passionate for God just as all of you are today.

For, behold, this same thing, your being grieved according to God, how much diligence it wrought in you, but what excusing of yourselves, but what indignation, but what fear, but what ardent desire, but what zeal, but what vengeance: in every way ye have proved yourselves to be pure in the matter.

and in their supplication for you, full of ardent desire for you, on account of the exceeding grace of God which is upon you.
