And the Lord said unto him, Arise, and go into the street which is called Straight, and inquire in the house of Judas for one called Saul, of Tarsus: for, behold, he prayeth, Arise, and go into the street which is called Straight - How very particular is this direction! And it was necessary that it should be so, that he might see the whole to be a Divine communication; the house was probably one in which Saul was accustomed to reside when at Damascus; and where he was known as a native of Tarsus.
Tarsus was a city of Cilicia, seated on the Cydnus, and now called Tarasso. It was, at one period, the capital of all Cilicia, and became a rival to Alexandria and Athens in the arts and sciences. The inhabitants, in the time of Julius Caesar, having shown themselves friendly to the Romans, were endowed with all the privileges of Roman citizens; and it was on this account that St. Paul claimed the rights of a Roman citizen; a circumstance which, on different occasions, was to him, and the cause in which he was engaged, of considerable service.
Behold, he prayeth - He is earnestly seeking to know my will, and to find the salvation of his soul; therefore, go speedily, and direct him. Some have laid needless stress on these words, as if they intimated, that "though Saul as a Pharisee had often said his prayers, yet he had never prayed them till now." This is not correct: he could himself testify that, while he was a Pharisee, he had lived in all good conscience towards God; and consequently, in that time, made many faithful and fervent prayers; but he was praying now for instruction, and his prayers were speedily answered.
