Bede the Venerable
Catena Aurea · Lukasevangelium 8
No man, when he hath lighted a candle, covereth it with a vessel, or putteth it under a bed; but setteth it on a candlestick, that they which enter in may see the light. For nothing is secret, that shall not be made manifest; neither any thing hid, that shall not be known and come abroad. Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken even that which he seemeth to have.
But the Lord ceases not to teach us to hearken to His word, that we may be able both to constantly meditate on it in our own minds, and to bring it forth for the instruction of others. Hence it follows, Take heed therefore how ye hear; for whosoever hath, to him shall be given. As if he says, Give heed with all your mind to the word which ye hear, for to him who has a love of the word, shall be given also the sense of understanding what he loves; but whoso hath no love of hearing the word, though he deems himself skilful either from natural genius, or the exercise of learning, will have no delight in the sweetness of wisdom; for oftentimes the slothful man is gifted with capacities, that if he neglect them he may be the more justly punished for his negligence, since that which he can obtain without labour he disdains to know, and sometimes the studious man is oppressed with slowness of apprehension, in order that the more he labours in his inquiries, the greater may be the recompense of his reward.
