1 Chronicles 4:4

Either they are other sons besides those mentioned 1Ch 2, or there is some variation in their names, which is most frequent among the Hebrews, as hath been oft proved. The father of Beth-lehem: this title is here given to the father, and 1 Chronicles 2:51, to Salma, his son, who had it either with or after his father.
