The warrior-king who conquered the enemies of Israel in a dark and desponding period; the sagacious statesman who gave unity to its various tribes, and formed them into a powerful monarchy; the matchless poet who bequeathed to all ages a lofty and beautiful psalmody; the saint, who with all his backslidings and inconsistencies was a man after God's own heart, --is well worthy of our study. David was the most illustrious of all the kings of whom the Jewish nation was proud, and was a striking type of a good man occasionally enslaved by sin, yet breaking its bonds and rising above subsequent temptations to a higher plane of goodness.
