'Realize' in the Bible

Then the king of Israel called all the elders of the land and said, "Please know and realize that this [man is] seeking trouble, for he sent to me for my women, my sons, my silver, and my gold, and I did not withhold [anything] from him."

Then a prophet approached Ahab king of Israel and said, “Thus says the Lord: ‘Have you seen all this great army? Behold, I will hand them over to you, and you shall know [without any doubt] that I am the Lord.’”
