Shammuah

The umbrella term Shammuah collects a single biblical figure: the firstborn of David's four sons by Bathsheba in Jerusalem. UPDV preserves this older spelling not in the verse text itself but in cross-reference; the verses themselves write the name as Shammua, with one parallel reading Shimea. For the broader name (which also covers a Reubenite spy, a Levite ancestor of Abda, and a priest of Joiakim's day), see Shammua.

Son of David in Jerusalem

The Samuel record names this son first in the list of David's Jerusalem children: "And these are the names of those who were born to him in Jerusalem: Shammua, and Shobab, and Nathan, and Solomon" (2Sa 5:14). The Chronicler's first list shifts the spelling and supplies the mother's name: "and these were born to him in Jerusalem: Shimea, and Shobab, and Nathan, and Solomon, four, of Bath-shua the daughter of Ammiel" (1Ch 3:5). The parallel duplicate-list in the same book returns to the form Shammua: "And these are the names of the children whom he had in Jerusalem: Shammua, and Shobab, Nathan, and Solomon" (1Ch 14:4).

The three references give two spellings (Shammua / Shimea) for the same firstborn of David and Bathsheba — full brother of Solomon.
