1 Chronicles 2:1,2 - Ellicott's Commentary On The Whole Bible

The sons of Israel. — The list is apparently taken from Genesis 35:23-26, where the heading is, “Now the sons of Jacob were twelve.” The chronicler omits the mothers, and puts Dan before instead of after Joseph and Benjamin, as if to hint that Dan was considered Rachel’s elder son. (See Genesis 30:6.) In the list at Genesis 46:9-23, Gad and Asher follow Zebulun, and Dan follows Joseph and Benjamin. Of course accident may have caused the transposition of Dan with Joseph and Benjamin in our list, especially as it otherwise agrees with Genesis 35:3-4.
