A covering - Hebrew "the covering," perhaps "the hanging" or "awning" at the door of the house, as the word seems to mean when spoken of the tabernacle.

Ground corn - Or "peeled barley," which she spread out as if for the purpose of drying it in the sun.

And the woman took and spread a covering over the well's mouth,.... This woman, very probably, was the man's wife of the house, as Abarbinel notes; who took a cloth, and spread it over the well's mouth, that it could not be seen or known that there was a well there:

and spread ground corn thereon: just taken out of the mill, before it was sifted, while in the bran; or corn unhusked, or just threshed out, in order to be dried in the sun, and then parched; or wheat bruised for that purpose: Josephus says (q) they were locks of wool she spread:

and the thing was not known; that the young men were in the well.

(q) Antiqu. l. 7. c. 9. sect. 7.

And the man's wife spread a covering (המּסך, the covering which she had close at hand) over the well (over the opening into the cistern), and scattered groats (ריפות, peeled barley: Proverbs 27:22) upon it, so that nothing was noticed. The Vulgate explanation is a very good one: "quasi siccans ptisanas" (as if drying peeled barley).

And {h} the woman took and spread a covering over the well's mouth, and spread ground corn thereon; and the thing was not known.

(h) Thus God sends help to his, in their greatest dangers.

17:19 Spread corn - Under pretence of drying it by the sun: which shews it was summer - time.

17:1-21 Here was a wonderful effect of Divine Providence blinding Absalom's mind and influencing his heart, that he could not rest in Ahithophel's counsel, and that he should desire Hushai's advice. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions. Ahithophel's former counsel was followed, for God intended to correct David; but his latter counsel was not followed, for God meant not to destroy him. He can overrule all counsels. Whatever wisdom or help any man employs or affords, the success is from God alone, who will not let his people perish.
