Augustine of Hippo
Catena Aurea · Lukasevangelium 11
And it came to pass, that, as he was praying in a certain place, when he ceased, one of his disciples said unto him, Lord, teach us to pray, as John also taught his disciples. And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth. Give us day by day our daily bread. And forgive us our sins; for we also forgive every one that is indebted to us. And lead us not into temptation; but deliver us from evil.
(in Enchirid. c. 116.) But what Matthew has placed at the end, But deliver us from evil, Luke has not mentioned, that we might understand it belongs to the former, which was spoken of temptation. He therefore says, But deliver us, not, “And deliverus,” clearly proving this to be but one petition,” Do not this, but this.” But let every one know that he is therein delivered from evil, when he is not brought into temptation.
