On the Sabbath day we went outside the city gate to the side of the river, where we thought there would be a place of prayer, and we sat down and began to speak to the women who had assembled there.

After we sighted Cyprus and left it behind on our port side, we sailed on to Syria and put in at Tyre, because the ship was to unload its cargo there.
