“And now brethren, I wote that through ignorance yee did it, as did also your rulers.”
1611 King James Version (KJV)
3:17 And now, brethren - A word full of courtesy and compassion, I know - He speaks to their heart, that through ignorance ye did it - which lessened, though it could not take away, the guilt. As did also your rulers - The prejudice lying from the authority of the chief priests and elders, he here removes, but with great tenderness. He does not call them our, but your rulers. For as the Jewish dispensation ceased at the death of Christ, consequently so did the authority of its rulers.
Ac 3:17 I wot. "I know". It was in ignorance of the majestic personality of Jesus that they slew him. Their rulers, ignorant also, might have known better had they not blinded themselves by prejudice.
