'Blankets' in the Bible

You who ride on light-colored female donkeys, who sit on saddle blankets, you who walk on the road, pay attention!

King David was very old; even when they covered him with blankets, he could not get warm.

As for your birth, on the day you were born your umbilical cord was not cut, nor were you washed in water; you were certainly not rubbed down with salt, nor wrapped with blankets.
