Mark 4:2, 13, 33

And He taught them many things in parables, and in His teaching He said to them

Then He said to them, “Do you not understand this parable? How will you understand and grasp the meaning of all the parables? [Matt 13:18-23; Luke 8:11-15]

With many such parables, Jesus spoke the word to them, as they were able to hear and understand it
