'It's' in the Bible

It's like the old proverb says: 'From evil people evil proceeds.' But my hand will not be against you.

When Saul recognized David's voice, he said, "Is that your voice, my son David?" David replied, "Yes, it's my voice, my lord the king."

Now it's your turn to listen to your servant! Let me set before you a bit of bread so that you can eat. When you regain your strength, you can go on your way."
