In my trouble my voice went up to the Lord, and my cry to my God: my voice came to his hearing in his holy Temple, and my prayer came to his ears.

And there David put up an altar to the Lord, making burned offerings and peace-offerings. So the Lord gave ear to his prayer for the land, and the disease came to an end in Israel.
