'Lay' in the Bible

So Amnon lay down and pretended to be sick. When the king came in to see him, Amnon said to the king, "Please let my sister Tamar come in so she can make a couple of cakes in my sight. Then I will eat from her hand."

Then the king stood up and tore his garments and lay down on the ground. All his servants were standing there with torn garments as well.
