And having destroyed seven nations in the land of Canaan, he gave them their land as an inheritance.

And there were certain men, seven sons of Sceva, Jewish high priest, who were doing this.

And having found out the disciples, we remained there seven days; who said to Paul by the Spirit not to go up to Jerusalem.

And leaving on the morrow, we came to Caesarea; and entering into the house of Philip the evangelist, who was of the seven, we abode with him.

And when the seven days were nearly completed, the Jews from Asia, having seen him in the temple, set all the crowd in a tumult, and laid hands upon him,

where, having found brethren, we were begged to stay with them seven days. And thus we went to Rome.
