'Down' in the Bible

Then she went down on her face to the earth, and said to him, Why have I grace in your eyes, that you give attention to me, seeing I am from a strange people?

So take a bath, and, after rubbing your body with sweet oil, put on your best robe, and go down to the grain-floor; but do not let him see you till he has come to the end of his meal.

So she went down to the grain-floor and did all her mother-in-law had said to her.
