'Straight' in the Bible

as it is written in the book of the words of the prophet Isaiah, "The voice of one crying out in the wilderness, 'Prepare the way of the Lord, make his paths straight!

Every valley will be filled, and every mountain and hill will be leveled, and the crooked will become straight, and the rough road [will become] smooth,

But [when] these [things] begin to happen, stand up straight and raise your heads, because your redemption is drawing near!"
