1 Chronicles 4:24

“The sons of Simeon, etc.] The account of whom, next to the tribe of Judah, is given before Reuben, because its inheritance lay in the tribe of Judah, (<061901>Joshua 19:1) his sons were Nemuel, the same with Jemuel, (<014610>Genesis 46:10) and Jamin, Jarib, Zerah, and Shaul; who, in the place referred to, is said to be the son of a Canaanitish woman; and Jarib and Zerah are the same with Jachin and Zohar there: and Obed is here omitted, it may be because he died without issue; (see <042612>Numbers 26:12,13).”

“OF SIMEON. (1Ch. 4:24-43) The sons of Simeon--They are classed along with those of Judah, as their possession was partly taken out of the extensive territory of the latter (Jos 19:1). The difference in several particulars of the genealogy given here from that given in other passages is occasioned by some of the persons mentioned having more than one name [compare Gen 46:10; Exo 6:15; Num 26:12].”

“4:24–8:40 After completing the genealogy of Judah’s descendants (2:3–4:23), the Chronicler turns to the records for the rest of the sons of Israel (cp. 2:1-2). 4:24-43 Simeon was Jacob’s second son; his tribe’s territory was in the southern part of Judah (Josh 19:1-9).”

“The sons of Simeon: This genealogy differs in many particulars from those in the parallel places; probably being occasioned by the same person's having several names. Nemuel: Gen 46:10; Exo 6:15, Jemuel Jarib: Num 26:12-14, Jachin Zerah: Gen 46:10, Zohar 1 Chronicles 4:27”

“The families of Simeon. - Of the six sons of Simeon, Gen 46:10 and Exo 6:15, only the five are here named who, according to Num 26:12-14, founded the families of this tribe. The third son, Ohad, is omitted even in Num 26:12 in the list of the families of Simeon, at the numbering of the people in the fortieth year of the journey through the wilderness, clearly only because the posterity of Ohad had either died out, or had so dwindled away that it could form no independent family. The names of the five sons agree with the names in Num 26:12-14, except in the case of Jarib, who in Num 26:12, which coincides here with Gen 46:10 and Exo 6:15, is called Jachin; יריב, consequently, must be looked…”
