'Grain' in the Bible

They entered the house as though they intended to obtain some grain and stabbed him in the abdomen. Then Rechab and his brother Baanah escaped.

So Absalom told his servants, "Observe that Joab's grain field lies next to mine. He has barley planted there. Go set it on fire." So Absalom's servants set the field on fire.

At this, Joab got up, went to Absalom's home, and demanded of him, "Why did your servants set fire to my grain field?"

The man's wife grabbed a sheet, covered the mouth of the well with it, and spread some dried grain over it. As a result, nobody could tell it was a hiding place.
