From my perspective, the (1 Chronicles 3:21) verse is Unclear.
I'm confused as who are the sons referenced when said verse mentions "...the sons of Rephaiah, the sons of Arnan, the sons of Obadiah, the sons of Shecaniah...".
Most of the other verses that describe the lineal descendants are quite clear, however, (1 Chronicles 3:21) verse is Unclear?
(1 Chronicles 3:19-24) New American Standard Bible (NASB)
19 The sons of Pedaiah were Zerubbabel and Shimei. And the [a]sons of Zerubbabel were Meshullam and Hananiah, and Shelomith was their sister; 20 and Hashubah, Ohel, Berechiah, Hasadiah and Jushab-hesed, five. 21 The [b]sons of Hananiah were Pelatiah and Jeshaiah, the sons of Rephaiah, the sons of Arnan, the sons of Obadiah, the sons of Shecaniah. 22 The [c]descendants of Shecaniah were Shemaiah, and the sons of Shemaiah: Hattush, Igal, Bariah, Neariah and Shaphat, six. 23 The [d]sons of Neariah were Elioenai, Hizkiah and Azrikam, three. 24 The sons of Elioenai were Hodaviah, Eliashib, Pelaiah, Akkub, Johanan, Delaiah and Anani, seven.
