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 F17 they were locks of wool she spread: 
 and the thing was not known;
 that the young men were in the well.
