The son of Shecaniah: Shemaiah. And the sons of Shemaiah: Hattush, Igal, Bariah, Neariah, and Shaphat, six.
David having nineteen sons, we may suppose them to have raised many noble families in Israel whom we never hear of in the history. But the scripture gives us an account only of the descendants of Solomon here, and of Nathan, Lu. 3. The rest had the honour to be the sons of David; but these only had the honour to be related to the Messiah.
Commenting on 1 Chronicles 3:10-24
And the sons of Shechaniah; Shemaiah: and the sons of Shemaiah; Hattush, and Igeal, and Bariah, and Neariah, and Shaphat, six. (g) So that Shemaiah was Shechaniah's natural son, and the other five his nephews and in all there were six.
The sons of Shemaiah - six - Five only are found in the text, and the versions give us no assistance; neither do the MSS. correct the place. If the father be not here included with his sons, some name must be lost out of the text.
