'Blanket' in the Bible

Jael came out to welcome Sisera. She said to him, "Stop and rest, my lord. Stop and rest with me. Don't be afraid." So Sisera stopped to rest in her tent, and she put a blanket over him.

Your splendor has been brought down to Sheol, as well as the sound of your stringed instruments. You lie on a bed of maggots, with a blanket of worms over you.

For the bed is too short to stretch out on, and the blanket is too narrow to wrap around oneself.
