'Know' in the Bible

Now there happened to be a certain woman who had been the wife of a member of the Guild of Prophets. She cried out to Elisha, "My husband who served you has died, and you know that your servant feared the LORD. But a creditor has come to take away my children into indentured servitude!"

Naaman went back to the man of God, along with his entire entourage, and stood before him. "Please look!" he said. "I know that there is no God in all the earth, except in Israel! So please, take a present from your servant."

so the king got up in the middle of the night and ordered his servants: "Let me explain what the Arameans have done to us. They know that we're hungry, so they've left their encampment to conceal themselves in the surrounding fields. They're telling themselves, "When they come out of the city, we'll capture them alive and enter the city!'"

"Why are you crying, sir?" Hazael asked. "Because I know the evil that you're about to bring on the Israelis," he replied. "You'll burn down their fortified cities, execute their young men with swords, dash to pieces their little ones, and you'll tear open their pregnant women!"

As Jehu was coming out to his master's attendants, one of them asked him, "Is everything all right? Why did this maniac visit you?" "You know the man and how he speculates," Jehu replied.

As a result, they reported to the king of Assyria, "Because the nations whom you exiled to live in the cities of Samaria don't know the law of the god of the land, he has sent lions among them. Look how the lions are killing them, because they don't know the law of the god of the land!"

Now, LORD our God, I'm praying that you will deliver us from his control, so that all the kingdoms of the earth may know that you alone, LORD, are God!"
