'Leader' in the Bible

One who breaks open the waywill advance before them;they will break out, pass through the gate,and leave by it.Their King will pass through before them,the Lord as their leader.

Jerusalem, why are you now shouting so loudly? Has your king disappeared? Has your wise leader been destroyed? Is this why pain grips you as if you were a woman in labor?

And speaking of evil, they practice it eagerly with both hands! Both leader and judge demand a bribe, the famous confess their perverted desires, and they scheme together.

Believe not in a friend, trust not in a leader, From her who is lying in thy bosom keep the openings of thy mouth.
