A covering; Hebrew, the cover; that is, the usual cover of the cistern, which had been taken off to let the young men descend into it. Over it she spread, not ground corn, but brayed or peeled corn (see Proverbs 27:22 ), probably barley groats. She was probably busy in removing the husks of the barley with a pestle in a mortar when Jonathan and Ahimaaz sought refuge with her; and thus her whole proceeding was so natural as to excite no suspicions.
