'Know' in the Bible

Boaz answered her, “Everything you have done for your mother-in-law since your husband’s death has been fully reported to me: how you left your father and mother and the land of your birth, and how you came to a people you didn’t previously know.

Wash, put on perfumed oil, and wear your best clothes. Go down to the threshing floor, but don’t let the man know you are there until he has finished eating and drinking.

Now don’t be afraid, my daughter. I will do for you whatever you say, since all the people in my town know that you are a woman of noble character.

I thought I should inform you: Buy it back in the presence of those seated here and in the presence of the elders of my people. If you want to redeem it, do so. But if you do not want to redeem it, tell me so that I will know, because there isn’t anyone other than you to redeem it, and I am next after you.”“I want to redeem it,” he answered.
