'Know' in the Bible

Boaz answered her, "It has fully been shown me, all that you have done to your mother-in-law since the death of your husband; and how you have left your father and your mother, and the land of your birth, and have come to a people that you didn't know before.

Now, my daughter, don't be afraid; I will do to you all that you say; for all the city of my people does know that you are a worthy woman.

Then she said, "Sit still, my daughter, until you know how the matter will fall; for the man will not rest, until he has finished the thing this day."

I thought to disclose it to you, saying, 'Buy it before those who sit here, and before the elders of my people.' If you will redeem it, redeem it; but if you will not redeem it, then tell me, that I may know. For there is no one to redeem it besides you; and I am after you." He said, "I will redeem it."
