Thou shalt meditate therein day and night... then thou shalt make thy way prosperous. — These words are taken up again in Psalms 1:2-3, and a blessing is pronounced on every man who takes Joshua’s position in relation to the written law of God (see Note, Joshua 1:1). Thus the true significance of Joshua’s position appears, and also the difference between Moses and all who followed him. Moses was the prophet “whom the Lord knew face to face.” Joshua and all his successors, from the least to the greatest, find their blessing and their portion in the careful study and fulfilment of the written word of God. It is also worthy of notice that God’s Word, from its very first appearance as a collective book (viz., the law), occupies the same position. It is supreme. It is set above Joshua. It is never superseded. And its authority is independent of its quantity. “The law of Moses,” “Moses and the prophets,” “The law, the prophets, and the Psalms,” are descriptions of the Bible differing in the quantity of the matter, but not differing in the authority they exercise or in their relation to the living church. “Blessed is he that readeth and they that hear the words of the prophecy of this book, and keep those things that are written therein,” are words that apply to Holy Scripture equally, in every stage, from the completion of the law of Moses to the completion of the entire book.
