Acts 18:18

Paul, having stayed after this many more days, took his leave of the brothers, and sailed from there for Syria, together with Priscilla and Aquila. He shaved his head in Cenchreae, for he had a vow.

And Paul after this tarried there yet a good while, and then took his leave of the brethren, and sailed thence into Syria, and with him Priscilla and Aquila; having shorn his head in Cenchrea: for he had a vow.
