'Straight' in the Bible

As it is written in the book of the words of Isaiah the prophet, "The voice of one shouting in the wilderness: 'Prepare the way for the Lord, make his paths straight.

Every valley will be filled, and every mountain and hill will be brought low, and the crooked will be made straight, and the rough ways will be made smooth,

But Jesus looked straight at them and said, "Then what is the meaning of that which is written: 'The stone the builders rejected has become the cornerstone'?

Then the Lord turned and looked straight at Peter, and Peter remembered the word of the Lord, how he had said to him, "Before a rooster crows today, you will deny me three times."
