'Know' in the Bible

David asked the young man who related the story, "How do you know that Saul and his son Jonathan are dead?"

You know Ner's son Abner came to mislead you, to learn your troop movements, and to learn everything you're doing!"

The king reminded his staff, "Don't you know that a prince and a great man has fallen today in Israel?

"What more can David say to you, and you surely know your servant, Lord GOD.

if the king starts to get angry and asks you, "Why did you get so near the city to fight? Didn't you know they would shoot from the wall?

But the king responded, "What do I have in common with you sons of Zeruiah? If he continues to curse and if the LORD has told him, "Curse David!' then who are you to be demanding to know "Why have you done this?'"

"You know how strong your father and his men are. They're as mad as a bear robbed of her cubs! Furthermore, your father is a skilled warrior. He won't stay with his army at night.

Then even men who would otherwise be as brave as lions will be scared, because every Israeli knows your father is a mighty man, and they know his men are valiant!

David replied, "What do you sons of Zeruiah have in common with me? You've become my enemies today! Should anyone be executed in Israel today? Don't you know that I've been reinstated as king over Israel today?"
