13 and Jesse begat his first-born Eliab, and Abinadab the second, and Shimea the third, 14 Nethaneel the fourth, Raddai the fifth, 15 Ozem the sixth, David the seventh, 16 and their sisters Zeruiah and Abigail. And sons of Zeruiah: Abishai, and Joab, and Asah-El—three. 17 And Abigail hath borne Amasa, and the father of Amasa 'is' Jether the Ishmeelite.
Matthew Henry's Commentary on 1 Chronicles 2:13-17
We are now come to the register of the children of Israel, that distinguished people, who were to dwell alone, and not be reckoned among the nations. But now, in Christ, all are welcome to his salvation who come to him; all have equal privileges according to their faith in him, their love and devotedness to him. All that is truly valuable consists in the favour, peace, and image of God, and a life spent to his glory, in promoting the welfare of our fellow-creatures.
