Of which son of David we nowhere else read; perhaps he might be the son of one of his concubines, or he might have two names:

and Abihail the daughter of Eliab the son of Jesse;
who was David's eldest brother. ( 1 Samuel 17:13 1 Samuel 17:28 ) . She must be a granddaughter or great-granddaughter of his.
