For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.(Mateo 13:15)

But blessed are your eyes, for they see: and your ears, for they hear.(Mateo 13:16)

For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.(Mateo 13:17)

When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart. This is he which received seed by the way side.(Mateo 13:19)

But he that received the seed into stony places, the same is he that heareth the word, and anon with joy receiveth it;(Mateo 13:20)

Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended.(Mateo 13:21)
