2 Samuel 23

2 Samuel 23:8
"He is like the most delicate worm of wood." [2 Samuel 23:8] This is said of the wisest leader of David's mighty men, whose name indeed is not mentioned in the Book of Kings, but in the Book of Chronicles he is called Jeshbaam and is noted to have been the son of Hachmoni (I Chron. XI). "He is like the most delicate worm of wood" (II Sam. XXIII, 8). This signifies both the man's martial strength and his modest civility, as he appeared, like a woodworm, indeed tender and fragile in his whole body, and even very small, yet nonetheless consumed and hollowed out the strongest wood, rendering it decayed. Hence, the woodworm takes its name from gnawing through wood. In the same way, he seemed to be affable to all at home, quiet and humble; yet in public battle, he showed himself to be a lion, strong and unbearable to his enemies. — Questions on the Book of Kings #9
2 Samuel 23:20
"He went down and struck the lion in the middle of the cistern." [2 Samuel 23:20] As it is said of Benaiah: And he went down and struck the lion in the middle of the cistern on a snowy day (Book VII, Antiquities, ch. 12), how this was done, Josephus recounts more clearly, because the cistern was indeed very deep, which in the wintertime, when everything was filled with snow, it too was leveled with an excessive heap of snow. When the lion, unbeknownst to danger, happened upon it and fell in, and being trapped there roared greatly, people ran to see what it was. And when Benaiah came with others to such a spectacle, he immediately jumped into the cistern, and attacked and killed the lion in the midst of the snow. — Questions on the Book of Kings #10
