Acts 18:24-25

24 "Meanwhile a Yavdan named Apollos, a native of Alexandria, came to Ephesus.   He was a learned man, with a thorough knowledge of the scriptures.

25 "He had been instructed in the way of [correctly] Yahveh, and he spoke with great fervor and taught about [correctly] Yahvsave accurately, though he knew only about the baptism of [correctly] Yahvhanan."
