'Crooked' in the Bible

In that day Jehovah, with his sore and great and strong sword, will visit leviathan the fleeing serpent, and leviathan the crooked serpent; and he will slay the monster that is in the sea.

Every valley shall be raised up, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough places a plain.

And I will bring the blind by a way that they know not, in paths that they know not will I lead them; I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them.

the way of peace they know not, and there is no judgment in their goings; they have made their paths crooked: whoso goeth therein knoweth not peace.
