Dimitri of Rostov
From this point, David launched military expeditions against the people dwelling in the wilderness, who were the initial adversaries of the Israelites.
And David and his men went up, and pillaged Gessuri, and Gerzi, and the Amalecites: for these were of old the inhabitants of the countries, as men go to Sur, even to the land of Egypt.
