Gevurot 19:1-2

Orthodox Jewish Bible

19 And it came about while Rav Apollos was in Corinth that Rav Sha’ul traveled through the upper regions and arrived at Ephesus, finding some of [Moshiach’s] talmidim there.

² And Rav Sha’ul said to them, "Did you receive the Ruach Hakodesh when you came to emunah?" But they said to Rav Sha’ul, "But we never heard that there is a Ruach Hakodesh!"
