Theophylact of Ohrid
Catena Aurea · Lukasevangelium 12
And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do. But I will forewarn you whom ye shall fear: Fear him, which after he hath killed hath power to cast into hell; yea, I say unto you, Fear him. Are not five sparrows sold for two farthings, and not one of them is forgotten before God? But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.
Or these five senses are sold for two farthings, that is, the New and Old Testament, and are therefore not forgotten by God. Of those whose senses are given up to the word of life that they may be fit for the spiritual food, the Lord is ever mindful.
