The closing lines of our chapter give us a very fine summing up of the practical teaching which has been engaging our attention. "Thou shalt fear the Lord thy God; Him shalt thou serve, and to Him shalt thou cleave, and swear by His name. He is thy praise, and He is thy God, that hath done for thee these great and terrible things, which thine eyes have seen. Thy fathers went down into Egypt with threescore and ten persons, and now the Lord hath made thee as the stars of heaven for multitude." (Ver. 20-22.) How thoroughly bracing is all this to the moral being! This binding of the heart to the Lord Himself by means of all that He is, and all His wondrous actings and gracious ways, is unspeakably precious. It is, we may truly say, the secret spring of all true devotedness. God grant that the writer and the reader may abidingly realize its motive power. CHAPTER XI. "Therefore thou shalt love the Lord thy God, and keep His charge, and His statutes, and His judgments, and His commandments, _alway_. And know ye this day; for I speak not with your children which have not known, and which have not seen the chastisements of the Lord your God, His greatness, His mighty hand, and His stretched-out arm, and His miracles, and His acts, which He did in the midst of Egypt unto Pharaoh the king of Egypt, and unto all his land; and what He did unto the army of Egypt, unto their horses, and to their chariots; how He made the water of the Red Sea to overflow them as they pursued after you, and how the Lord hath destroyed them unto this day; and what He did unto you in the wilderness, until ye came into this place; and what He did unto Dathan and Abiram, the sons of Eliab, the son of Reuben; how the earth opened her mouth, and swallowed them up, and their households, and their tents, and all the substance that was in their possession, in the midst of all Israel; but your eyes have seen all the great acts of the Lord which He did." Moses felt it to be of the very highest importance that all the mighty acts of Jehovah should be kept prominently before the hearts of the people, and deeply engraved on the tablets of their memory. The poor human mind is vagrant, and the heart volatile, and notwithstanding all that Israel had seen of the solemn judgments of God upon Egypt and upon Pharaoh, they were in danger of forgetting them, and losing the impression which they were designed and eminently fitted to make upon them. It may be we feel disposed to wonder how Israel could ever forget the impressive scenes of their history in Egypt from first to last--the descent of their fathers thither as a mere handful, their steady growth and progress as a people, spite of formidable difficulties and hindrances, so that from the insignificant few, they had become, by the good hand of their God upon them, as the stars of heaven for multitude.
