'Realize' in the Bible

Is this not the time of the wheat harvest? I will call on the Lord so that he makes it thunder and rain. Realize and see what a great sin you have committed before the Lord by asking for a king for yourselves."

This very day the Lord will deliver you into my hand! I will strike you down and cut off your head. This day I will give the corpses of the Philistine army to the birds of the sky and the wild animals of the land. Then all the land will realize that Israel has a God

Saul became angry with Jonathan and said to him, "You stupid traitor! Don't I realize that to your own disgrace and to the disgrace of your mother's nakedness you have chosen this son of Jesse?

Look, my father, and see the edge of your robe in my hand! When I cut off the edge of your robe, I didn't kill you. So realize and understand that I am not planning evil or rebellion. Even though I have not sinned against you, you are waiting in ambush to take my life.

Now look, I realize that you will in fact be king and that the kingdom of Israel will be established in your hand.
