'Offspring' in the Bible

Solomon’s son was Rehoboam. Abijah was his son, Asa his son, Jehoshaphat his son,

All these were sons (descendants) of Asher, heads of their fathers’ houses, choice men, courageous men, chiefs of the leaders. Their number, enrolled by genealogies for service in war, was 26,000 men.

O seed of Israel His servant,Children of Jacob, His chosen ones!

And it shall come to pass that when your days are completed and you must go to be with your fathers [in death], I will raise up one of your descendants after you, one of your own sons; and I will establish his kingdom.
