“And Benaiah the son of Jehoiada, the son of a valiant man, of Kabzeel, who had done many acts, he slew two lionlike men of Moab: he went down also and slew a lion in the midst of a pit in time of snow:”
King James Version (KJV)
23:19 Attained not - He fell short of them in strength and valour.
23:21 Pit - Where he put himself under a necessity, either of killing, or being killed. Of snow - When lions are most fierce, both from the sharpness of their appetite in cold seasons, and from want of provisions.
