'That's' in the Bible

“I am the seer,” Samuel answered. “Go up ahead of me to the high place and eat with me today. When I send you off in the morning, I’ll tell you everything that’s in your heart.

Saul did not say anything that day because he thought, “Something unexpected has happened; he must be ceremonially unclean—yes, that’s it, he is unclean.”

He said, ‘Please let me go because our clan is holding a sacrifice in the town, and my brother has told me to be there. So now, if you are pleased with me, let me go so I can see my brothers.’ That’s why he didn’t come to the king’s table.”

That’s why all of you have conspired against me! Nobody tells me when my own son makes a covenant with Jesse’s son. None of you cares about me or tells me that my son has stirred up my own servant to wait in ambush for me, as is the case today.”
