Acts 23:1-5

And Paul said, "I was not aware, brethren, that he was high priest; for it is written, 'you shall not speak evil of a ruler of your people.'"

This is an interesting story because the high priest in charge was doing something wrong (commanding Paul to be beaten before he was condemned). And Paul called him on it, but took it back when he realized it was the high priest. Even if my leaders (in church, my school, in government) are wrong, it's still not my place to speak evil of them or about them. It's about respect for authority, because nobody is in authority unless God places them there. This is hard for me to do, especially if I disagree with the way people in authority are doing things. They are there by God's command. I've got to deal with it and work with them, not against.
