Charles Ellicott Commentary 1 Chronicles 9:36

"and his first-born son Abdon, and Zur, and Kish, and Baal, and Ner, and Nadab," — 1 Chronicles 9:36 (ASV)

Zur. —“Rock,” a Divine title. (Compare Pedahzur, “the Rock has ransomed; ” Zurishaddai, “the Rock is the Lofty One; ” if we may connect the difficult Shaddai with the Assyrian term sadu, “mountain.” But it seems better to explain it from the root shâdâh, “to pour out,” which is found in Aramaic and Arabic; so that Shaddai would signify “giver of rain.” (Compare Joel 2:23.))

Baal has been compounded with Nadab, to form a single name, Baal-nadab, “Baal is prince.” (Compare Baal-gad, “Baal is Gad; ” Baal-hanan, “Baal is bounteous,” 1 Chronicles 1:49). In that case Ner is out of place.
