Gevurot 18:18-20

Orthodox Jewish Bible

¹⁸ But Rav Sha’ul still remained a number of yamim and then took leave of the Achim b’Moshiach, and was sailing away to Syria; and with him were Priscilla and Aquila. In Cenchrea he cut his hair, for he had taken a neder (vow). [BAMIDBAR 6:2,5,18]

¹⁹ Then they arrived in Ephesus, and Rav Sha’ul left them there, but he joined the minyan in the shul and debated with the Yehudim.

²⁰ And when they were asking Rav Sha’ul to stay for a longer time, he did not give his consent.
