John Gill Commentary Luke 22:68

"and if I ask [you], ye will not answer." — Luke 22:68 (ASV)

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 anything to you.
