TSK · 1 Chronicles 27:32

But Amnon had a friend, whose name was Jonadab, the son of Shimeah, David's brother; and Jonadab was a very subtle man.

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.
