“That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them.”
Mark 4:12 — Greek Interlinear
Church Fathers on Mark 4:12
Although the Lord appears in the transactions mentioned above to neglect His mother, nevertheless He honours her; since on her account He goes forth about the borders of the sea.
For if we look into the Gospel of Matthew, it appears that this same teaching of the Lord at the sea, was delivered on the same day as the former. For after the conclusion of the first sermon, Matthew immediately subjoins, saying, 'The same day went Jesus out of the house, and sat by the sea-side.'
But He began to teach at the sea, that the place of His teaching might point out the bitter feelings and instability of His hearers.
