Lest strangers be filled with your strength, etc. Lest you assist the deeds of demons, if you lend either the ingenuity of your mind or the strengths of your body to perform crimes; and you multiply the household of strangers, that is, the number of the lost, by adding yourself. And beautifully he said: Let your labors be in the house of a stranger, because there are those who, according to the prophet, labor to act wickedly. And would that it were hidden how much labor heretics have undergone against the Church.
[AD 735] Bede on Proverbs 5:10
