This is the number of the mighty men whom David had: Jashobeam, the son of a Hachmonite, the chief of the thirty; he lifted up his spear against three hundred and killed them at one time.
Benaiah, one of the second three along with Abishai had done many acts. He killed two lion like men of Moab. Now whatever that may be. Probably hairy guys with bushy hair and beards.
