'Lay' in the Bible

And Boaz ate and drank [until] his heart was {merry} [and then] he came to lie at the end of the grain heap. And she came in quietly and {uncovered} his feet and lay down.

So she lay at his feet until morning and got up before {anyone could recognize each other}. And he said, "It must not be known that {you} came [to] the threshing floor."
