1 Chronicles 6:20-21 -

(A) These verses apparently give seven lineal descendants of Gershom, through his eldest son Libni . The question is whether this list of seven is part of the longer list of thirteen from Gershom ( 1 Chronicles 6:39-43 ). terminating with Asaph; and it seems impossible to decide the question satisfactorily. From the occurrence of the name Shimei in this latter, though in the wrong place, viz. after Jahath in the descending order, instead of before him, some think, Keil and Zockler among them, that it is a line from Shimei, the brother of Libni, and second son of Gershom. If this be so, the occurrence of three names, the same and in the same order, is a thing to be remarked, though possible enough in itself. But if not, then either the names Joah, Iddo, Jeaterai , in the former list, must be interchangeable with Ethan , Adaiah , Ethni , respectively in the latter (a thing which the similarity of the Hebrew letters might render credible), while the Shimei of 1 Chronicles 6:42 is omitted from 1 Chronicles 6:20 , and the Libni of 1 Chronicles 6:20 from 1 Chronicles 6:43 ; or the one list must pick up some links and leave others, and the other do likewise, whilst those taken the same by both are in the minority. This last supposition may be the more probable, though not free from difficulty. Zimmah. Beside the uncertainty of the identity of this Zimmah with the same name in 1 Chronicles 6:42 , it is very remarkable that we find a Zimmah, also father of a Joah , in 2 Chronicles 29:12 ; also in this same passage we find three other reproductions of a similar kind —father and son-of what have first been found in this sixth chapter, viz. "Mahath, son of Amasai" ( 2 Chronicles 29:35 ); "Joel, son of Azariah" (verse 36); "Kish, son of Abdi" (verse 44). It seems as though the individual descendant was quoted in these instances by the name of the ancestor at a certain point.
