'Know' in the Bible

The sons of Eli [Hophni and Phinehas] were worthless (dishonorable, unprincipled) men; they did not know [nor respect] the Lord

Now Samuel did not yet know [or personally experience] the Lord, and the word of the Lord was not yet revealed [directly] to him.

But watch, if it goes up by the way of its own territory to Beth-shemesh, then [you will know that] He has done us this great evil. But if not, then we will know that it was not His hand that struck us; this disaster happened to us by chance.”

Is it not [the beginning of the] wheat harvest today? I will call to the Lord and He will send thunder and rain; then you will know [without any doubt], and see that your evil which you have done is great in the sight of the Lord by asking for yourselves a king.”

and Ahijah the son of Ichabod’s brother Ahitub the son of Phinehas, the son of Eli, the Lord’s priest at Shiloh, was wearing the ephod. And the people did not know that Jonathan had gone.

Now Eliab his oldest brother heard what he said to the men; and Eliab’s anger burned against David and he said, “Why have you come down here? With whom did you leave those few sheep in the wilderness? I know your presumption (overconfidence) and the evil of your heart; for you have come down in order to see the battle.”

This day the Lord will hand you over to me, and I will strike you down and cut off your head. And I will give the corpses of the army of the Philistines this day to the birds of the sky and the wild beasts of the earth, so that all the earth may know that there is a God in Israel,

and that this entire assembly may know that the Lord does not save with the sword or with the spear; for the battle is the Lord’s and He will hand you over to us.”

But David vowed again, saying “Your father certainly knows that I have found favor in your sight, and he has said, ‘Do not let Jonathan know this, or he will be worried.’ But truly as the Lord lives and as your soul lives, there is hardly a step between me and death.”

Then Jonathan said to David, “The Lord, the God of Israel, is my witness! When I have sounded out my father about this time tomorrow, or the third day, behold, if he has a good feeling toward you, shall I not then send word to you and make it known to you?

Then Saul’s anger burned against Jonathan and he said to him, “You son of a wayward, rebellious woman! Do I not know that you have chosen the son of Jesse [over me] to your own shame, and to the shame of your mother’s nakedness?

David said to Ahimelech the priest, “The king has commissioned me with a matter and has told me, ‘Let no one know anything about the matter for which I am sending you and with which I have commissioned you. I have directed the young men to a certain place.’

And David went from there to Mizpah of Moab; and he said to the king of Moab, “Please let my father and my mother come [out of Judah] and stay with you until I know what God will do for me.”

Go now, be very persistent and investigate, and see where his haunt is and who has seen him there; for I am told he is very cunning.

Look, my father! Indeed, see the hem of your robe in my hand! Since I cut off the hem of your robe and did not kill you, know and understand [without question] that there is no evil or treason in my hands. I have not sinned against you, though you are lying in wait to take my life.

Now, behold, I know that you will certainly be king and that the kingdom of Israel will be established in your hand.

So should I take my bread and my water and my meat that I have slaughtered for my shearers, and give it to men when I do not know where they are from?”

Now then, know this and consider what you should do, for evil is [already] planned against our master and against all his household; but he is such a worthless and wicked man that one cannot speak [reasonably] to him.”

David said to Achish, “All right, you shall know what your servant can do.” So Achish said to David, “Therefore I will make you my bodyguard for life.”

But the woman said to him, “See here, you know what Saul has done, how he has cut off (eliminated) those who are mediums and spiritists from the land. So why are you laying a trap for my life, to cause my death?”

Achish answered David, “I know that you are blameless in my sight, like an angel of God; nevertheless the commanders of the Philistines have said, ‘He must not go up with us to the battle.’
