Ambrose of Milan
Catena Aurea · Lukasevangelium 6
And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God. And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles; Simon, (whom he also named Peter,) and Andrew his brother, James and John, Philip and Bartholomew, Matthew and Thomas, James the son of Alphæus, and Simon called Zelotes, And Judas the brother of James, and Judas Iscariot, which also was the traitor.
Let not thy ears be open to deceit, that thou shouldest think that the Son of God prays from want of strength, that He may obtain what He could not perform; for being Himself the Author of power, the Master of obedience, He leads us by His own example to the precepts of virtue.
