'Judaism' in the Bible

This suggestion pleased the whole group. So they chose Stephen, a man full of faith and the Holy Spirit, Philip, Prochorus, Nicanor, Timon, Parmenas, and Nicolaus, a gentile convert to Judaism from Antioch.

I advanced in Judaism beyond many of my contemporaries, because I was far more zealous for the traditions of my ancestors.

For there are many people who are rebellious, especially those who are converts from Judaism. They speak utter nonsense and deceive people.
