David spoke with satisfaction of the Lord as something that someone had given him. He compared God to a valuable inheritance passed on to him by his ancestors, and to wine in a cup that brings great joy and satisfaction to the one who drinks it. He also gave God credit for supporting him in his lot in life. The lines marking the boundaries of David"s inheritance (i.e, God"s will) had turned out to be good lines since they prescribed a great inheritance. Compared to a piece of real estate such as the ones given to the Israelite tribes when they entered the Promised Land, David had received a pleasant lot. He viewed his inheritance as a beautiful piece of property. Obviously, he was pleasantly content with God and found great delight in Him. [source][source][source]
