'It's' in the Bible

Shadrach, Meshach, and Abednego answered King Nebuchadnezzar, "It's not necessary for us to respond in this matter.

it's you, your majesty! You've become great and strong, your greatness has grown to the heavens, and your dominion reaches to the distant parts of the earth.

As it's written in the Law of Moses, all this calamity has befallen us, but we still haven't sought the LORD our God by turning from our lawlessness to pay attention to your truth.
