Augustine of Hippo
Catena Aurea · Matthäusevangelium 7
Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
(ubi sup.) Otherwise; when He commanded not to give the holy thing to dogs, and not to cast pearls before swine, the hearer conscious of his own ignorance might say, Why do you thus bid me not give the holy thing to dogs, when as yet I see not that I have any holy thing? He therefore adds in good season, Ask, and ye shall receive.
