Bede the Venerable
Catena Aurea · Lukasevangelium 9
And it came to pass, that, as they went in the way, a certain man said unto him, Lord, I will follow thee whithersoever thou goest. And Jesus said unto him, Foxes have holes, and birds of the air have nests; but the Son of man hath not where to lay his head. And he said unto another, Follow me. But he said, Lord, suffer me first to go and bury my father. Jesus said unto him, Let the dead bury their dead; but go thou and preach the kingdom of God. And another also said, Lord, I will follow thee; but let me first go bid them farewell, which are at home at my house. And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God. It follows, And Jesus says to him, The foxes have holes, &c.
: To put one’s hand to the plough, is also, (as it were by a certain sharp instrument,) by the wood and iron of our Lord’s passion, to wear away the hardness of our heart, and to open it to bring forth the fruits of good works. But if any one, having begun to exercise this, delights to look back with Lot’s wife to the things which he had left, he is deprived of the gift of the kingdom to come.
