Job 1:2 New English Translation

²Seven^[a] sons and three daughters were born to him.^[b]

Job 1:2 sn The numbers used in the chapter, seven, three, and five, carry the symbolism in the Bible of perfection and completeness (see J. J. Davis, Biblical Numerology). Job’s “seven sons” are listed first because in the East sons were considered more valuable than daughters (recall Ruth, who is “better than seven sons” [Ruth 4:15]).
Job 1:2 tn The verb begins the sentence: “and there were born.” This use of the preterite with vav (ו) consecutive, especially after the verb הָיָה (hayah, “to be”), is explanatory: there was a man…and there was born to him…” (IBHS 551-52 §33.2.2b).
