And if I also ask you - Concerning the Christ, in case ye cannot give me such an answer as may prove I am not the Christ, ye will not let me go; for I know ye are determined to put me to death.

And if I also ask you,.... Or enter into a discourse on this subject, and require an answer to the arguments, proving me to be the Messiah, or desire to know what objections can be made thereunto:
you will not answer me: fairly and directly, or go into a serious and sober conversation on this head: nor let me "go"; or dismiss me, though I should appear to be the Messiah, or ever so free from the charge of blasphemy and sedition; you are resolved, right or wrong, to detain me in bonds, and take away my life; so that it signifies nothing saying any thing to you.

Art thou then the Son of God? To this he answered directly, and on this they condemned him. The charge was blasphemy in saying that he was the Son of God.
