“For if they do these things in a green tree, what shall be done in the dry?”
King James Version (KJV)
23:31 If they do these things in the green tree, what shall be done in the dry? - Our Lord makes use of a proverbial expression, frequent among the Jews, who compare a good man to a green tree, and a bad man to a dead one: as if he had said, If an innocent person suffer thus, what will become of the wicked? Of those who are as ready for destruction as dry wood for the fire?
Lu 23:31 If they do these things, etc. A proverb, meaning here, "If the rulers and the Romans crucify the Messiah of the nation, the Hope of Israel, what shall they do to the nation itself"? What they would do was seen in less than forty years.
