'Known' in the Bible

And Boaz answereth and saith to her, 'It hath thoroughly been declared to me all that thou hast done with thy mother-in-law, after the death of thy husband, and thou dost leave thy father, and thy mother, and the land of thy birth, and dost come in unto a people which thou hast not known heretofore.

and thou hast bathed, and anointed thyself, and put thy garments upon thee, and gone down to the threshing-floor; let not thyself be known to the man till he complete to eat and to drink;

and it cometh to pass when he lieth down, that thou hast known the place where he lieth down, and hast gone in, and uncovered his feet, and lain down, -- and he doth declare to thee that which thou dost do.'

And she lieth down at his feet till the morning, and riseth before one doth discern another; and he saith, 'Let it not be known that the woman hath come into the floor.'
