2 Samuel 23:8, "These are the names of David's mighty men: Josheb-Basshebeth, a Tahkemonite, was chief of the Three; he raised his spear against eight hundred men, whom he killed in one encounter."

1 Chronicles 11:11, "...this is the list of David's mighty men: Jashobeam, a Hacmonite, was chief of the officers; he raised his spear against three hundred men, whom he killed in one encounter."

According to 2 Samuel chapter 23, David's mighty men were led by Josheb-Basshebeth, a Tahkemonite, who killed 800 men in one encounter, however, the same account in 1 Chronicles chapter 11 records David's chief as Jashobeam, a Hacmonite, who killed 300 men in one encounter.
