'It's' in the Bible

Achan answered Joshua, "It's true. I'm the one who sinned against the LORD God of Israel.

Look at our bread: it was still warm when we took it from our houses as our food for our journey on the very day we set out to come to you. But now, look how it's dry and moldy.

but the hill country will also belong to you. Even though it's a forest, you will clear it and possess it to its farthest borders. You'll drive out the Canaanites, even though they have iron chariots and even though they're strong."

If you think it's the wrong thing for you to serve the LORD, then choose for yourselves today whom you will serve the gods whom your ancestors served on the other side of the Euphrates River, or the gods of the Amorites in whose territories you are living. But as for me and my household, we will serve the LORD."
