Mark 4:13

10 And when he was alone, those around him with the twelve asked him about the parables. 11 And he said to them, “To you has been given the secret of the kingdom of God, but for those outside everything is in parables, 12 so that “‘they may indeed see but not perceive, and may indeed hear but not understand, lest they should turn and be forgiven.’”

13 And he said to them, “Do you not understand this parable? How then will you understand all the parables? 14 The sower sows the word. 15 And these are the ones along the path, where the word is sown: when they hear, Satan immediately comes and takes away the word that is sown in them. 16 And these are the ones sown on rocky ground: the ones who, when they hear the word, immediately receive it with joy.
