And there were born unto him,.... By his wife, in lawful wedlock, who was now living, and after mentioned: seven sons and three daughters; next to his religious character, his graces, and spiritual blessings, and as the chief of his outward mercies and enjoyments, his children are mentioned; and which are indeed blessings from the Lord, and such as good men, and those that fear the Lord, are sometimes blessed with, see Psa 127:3 and to have a numerous offspring was always esteemed a very great favour and blessing, and as such was reckoned by Job; who, having so many sons, might hope to have his name perpetuated by them, as well as his substance shared among them; and having so many daughters, he might please himself with the thought of marrying them into families, which would strengthen his friendship and alliance with them; just the same number of sons and daughters had Bacchaeus, the third king of Corinth (y).
