And I went out after him
 Whether a lion or a bear; but mention after being made of his beard, a lion rather is meant: 
 and smote him;
 with his fist, or rather with his shepherd's staff: 
 and delivered [it] out of his mouth;
 snatched it out from thence, or obliged him to drop it, by beating him: 
 and when he arose against me;
 after he had let go the lamb, threatening to tear him in pieces for attempting to disturb him in his prey, and take it away from him; 
 I caught [him] by his beard;
 such as lions have; hence a lion is often called in Homer F7 (liv heugeneiov) , the well-bearded lion. Kimchi thinks the beard with the nether jaw is meant, which David caught hold on: 
 and smote him, and slew him;
 tore him to pieces, as Samson did, ( Judges 14:5 Judges 14:6 ) , or slew him with some weapon in his hand.
