'It's' in the Bible

Jonah told them, "Pick me up and toss me into the sea. Then the sea will calm down for you, because I know that it's my fault that this mighty storm has come upon you."

Therefore, LORD, please kill me, because it's better for me to die than to live!"

As the sun was rising, God appointed a scorching east wind. The sun beat down so much on Jonah’s head that he almost fainted, and he wanted to die. He said, “It’s better for me to die than to live.”
