'Knew' in the Bible
The family got up early the next morning, worshiped before the Lord, and returned to their home in Ramah. Elkanah knew Hannah his wife, and the Lord remembered her [prayer].
Now I have told him that I am about to judge his house forever for the sinful behavior which he knew [was happening], because his sons were bringing a curse on themselves [dishonoring and blaspheming God] and he did not rebuke them.
And all Israel from Dan [in the north] to Beersheba [in the south] knew that Samuel was appointed as a prophet of the Lord.
Now when all who knew Saul previously saw that he actually prophesied now [by inspiration] with the prophets, the people said one to another, “What has happened to [Saul, who is nobody but] the son of Kish? Is Saul also among the prophets?”
When Saul saw and knew that the Lord was with David, and that Michal, his daughter, loved him,
Jonathan said, “Far be it from [happening to] you! In fact, if I indeed learn that my father has decided to harm you, would I not tell you about it?”
Then Saul hurled his spear at him to strike him down, so Jonathan knew [without any doubt] that his father had decided to put David to death.
But the boy was not aware of anything; only Jonathan and David knew about the matter.
And the king said to the guards who stood around him, “Turn around and kill the priests of the Lord, because their loyalty also is with David, and because they knew that he was fleeing and did not inform me.” But the servants of the king were not willing to put out their hands to attack the Lord’s priests.
Then David said to Abiathar, “I knew that day, when Doeg the Edomite was there, that he would certainly tell Saul. I have brought about the death of everyone in your father’s household (extended family).
But David knew that Saul was plotting evil against him; and he said to Abiathar the priest, “Bring the ephod here.”
So David took the spear and the jug of water from beside Saul’s head, and they left, and no one saw or knew nor did anyone awaken, because they were all sound asleep, for a deep sleep from the Lord had fallen on them.
Then Saul recognized David’s voice and said, “Is this your voice, my son David?” And David said, “It is my voice, my lord the king!”
