'Proselyte' in the Bible

“Woe to you, [self-righteous] scribes and Pharisees, hypocrites, because you travel over sea and land to make a single proselyte (convert to Judaism), and when he becomes a convert, you make him twice as much a son of hell as you are.

The suggestion pleased the whole congregation; and they selected Stephen, a man full of faith [in Christ Jesus], and [filled with and led by] the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas, and Nicolas (Nikolaos), a proselyte (Gentile convert) from Antioch.
