'Know' in the Bible

And Boaz answered and said to her, "All that you have done for your mother-in-law after the death of your husband was fully told to me. [How] you left your father and mother and the land of your birth, and you went to a people that you did not know {before}.

And she said, "Wait, my daughter, until you know how the matter turns out, for the man will not rest but will settle the matter today."

And I thought {I would tell you} and say, '{Buy it in the presence of} those sitting and before the elders of my people,' if you want to redeem [it], redeem [it]. But if you do not want to redeem, tell me so that I may know, for there is no one except you to redeem [it], and I [am] after you." And he said, "I want to redeem [it]."
