"Therefore thou shalt keep the commandments of the Lord thy God, to walk in His ways, and to fear Him." The word "therefore" had a retrospective and prospective force. It was designed to lead the heart back over the past dealings of Jehovah, and forward into the future. They were to think of the marvelous history of those forty years in the desert,--the teaching, the humbling, the proving, the watchful care, the gracious ministry, the full supply of all their need, the manna from heaven, the stream from the smitten rock, the care of their garments, and of their very feet, the wholesome discipline for their moral good. What powerful moral motives were here for Israel's obedience! But this was not all: they were to look forward into the future; they were to anticipate the bright prospect which lay before them; they were to find in the future, as well as in the past and the present, the solid basis of Jehovah's claims upon their reverent and whole-hearted obedience. "For the Lord thy God bringeth thee into a good land, a land of brooks of water, of fountains and depths that spring out of valleys and hills; a land of wheat, and barley, and vines, and fig-trees, and pomegranates, a land of oil olive, and honey; a land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass." How fair was the prospect! how bright the vision! How marked the contrast to the Egypt behind them and the wilderness through which they had passed! The Lord's land lay before them in all its beauty and verdure, its vine-clad hills and honeyed plains, its gushing fountains and flowing streams. How refreshing the thought of the vine, the fig-tree, the pomegranate, and the olive! How different from the leeks, onions, and garlic of Egypt! Yes, all so different! It was the Lord's own land: this was enough. It produced and contained all they could possibly want. Above its surface, rich profusion; below, untold wealth--exhaustless treasure.
