Acts 3:16
Now, fellow Israelites, I know that you acted in ignorance, as did your leaders. — Peter shows mercy: the crowd's action (putting Jesus to death) was in ignorance (agnoeo, not know, lack understanding), echoing Jesus' own prayer from the cross ('Father, forgive them, for they do not know what they are doing,' Luke 23:34). The ignorance doesn't excuse but it opens space for repentance. The leaders' ignorance is significant; even rulers and authorities were operating without full understanding.
