'Know' in the Bible

"What more can David say to you about how you are honoring your servant, and you surely know your servant.

"Now as for you, my son Solomon, get to know the God of your father. Serve him with a sound heart and a devoted soul, because the LORD is searching every heart, every plan and thought. He will be found by you, assuming you are seeking him, but if you abandon him, he will abandon you forever.

And I know, God, that it is you who searches the heart and you who finds pleasure in righteousness. With a righteous heart I have freely given all these things, and now I have seen all of these people of yours giving freely and joyfully to you!
