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.
Lastly, the numbering of the hairs is not to be taken with reference to the act of reckoning, but to the capability of knowing. Yet they are well said to be numbered, because those things which we wish to preserve we number.
