Gevurot 13:1-3

Orthodox Jewish Bible

13 Now there was in Antioch there among the Moshiach’s Kehillah nevi’im and morim: Bar-Nabba, and Shimon called Niger, and Lucius from Cyrene, and Menachem (brought up with Herod the tetrarch) and Rav Sha’ul.

² They were ministering to Adonoi and under a tzom when the Ruach Hakodesh said to them, “Set apart for Me Bar-Nabba and Sha’ul for the avodas kodesh ministry to which I have called them.” [DIVREY HAYAMIM BAIS 13:10; 35:3; YECHEZKEL 40:46; 44:16; 45:4]

³ Then, having continued the tzom and having davened and having laid their hands upon them, they sent them off.
