Deuteronomy 11:6

There is no mention here of Korah: see on Numbers 16.

10, 11. The fields in Egypt require to be watered artificially. The water is raised from the lakes or from the Nile by means of pumps worked by the foot. But the expression wateredst it with thy foot may refer to the practice of diverting the water into numberless little channels by breaking down the separating ridges, or by opening and shutting the sluices, with the foot. The land of Canaan requires no such human devices to render it fruitful. It drinketh water of the rain of heaven. It enjoys the direct blessing of God. A common Palestinian salutation during rain is, 'May God protect you while He is blessing the fields.'
