Therefore it is that after the Bible has shown us (in the Book of Ruth) worthy Boaz standing among his reapers in the barley field, it goes on to show us Boaz's great-grandson, David, a worthy man likewise, but of a very different life, marked out by God from his youth for strange and desperate deeds; killing, as a mere boy, a lion and a bear, overthrowing the Philistine giant with a sling and a stone, captain of a band of outlaws in the wilderness, fighting battles upon battles; and at last a king, storming the mountain fortress of Jerusalem, and setting up upon Mount Zion, which shall never be removed, the Throne of David. A strange man, and born into a strange time. You all know the first part of David's history--how Samuel secretly anoints David king over Israel, and how the Spirit of the Lord comes from that day forward upon the young lad (1 Samuel xvi. 12). How king Saul meanwhile fell into dark and bad humours. How the Spirit of the Lord--of goodness and peace of mind--goes from him, and an evil spirit from the Lord troubles him. Then how young David is sent for to play to him on his harp (1 Samuel xvi.), and soothe his distempered mind. Already we hear of David as a remarkable person; we hear of his extraordinary beauty, his skill in music; we hear, too, how he is already a man of war, and a mighty valiant man, and prudent in matters, and the Lord is with him. Then follows the famous story of his killing Goliath the Philistine (1 Samuel xvii.). Poor, distempered Saul, it seems, had forgotten him, though David had cured his melancholy with his harp-playing, and had actually been for a while his armour-bearer, for when he comes back with the giant's head, Saul has to ask Abner who he is; but after that he will let him go no more home to his father.
