"The Tachmonite that sat in the seat," chief among Davids captains, ( 2 Samuel 23:8 ) Isa in 1Chr 11:11 called "Jashobeam an Hachmonite," or, as the margin gives it, "son of Hachmoni." Kennicott has shown that the words translated "he that sat in the seat" are a corruption of Jashobeam, and that "the Tachmonite" is a corruption of the "son of Hachmoni," which was the family or local name of Jashobeam. Therefore he concludes "Jashobeam the Hachmonite" to have been the true reading.
