1:22 Not back - Without effect: their arrows shot from their bow, and their swords did seldom miss, and commonly pierced fat, and flesh, and blood, and reached even to the heart and bowels. Returned not, and c. - But filled and glutted with blood: for the sword is metaphorically said to have a mouth, which we translate an edge; and to devour. And this their former successfulness is mentioned as an aggravation of their last infelicity.
1:17-27 Kasheth, or the bow, probably was the title of this mournful, funeral song. David does not commend Saul for what he was not; and says nothing of his piety or goodness. Jonathan was a dutiful son, Saul an affectionate father, therefore dear to each other. David had reason to say, that Jonathan's love to him was wonderful. Next to the love between Christ and his people, that affection which springs form it, produces the strongest friendship. The trouble of the Lord's people, and triumphs of his enemies, will always grieve true believers, whatever advantages they may obtain by them.
