In Job's testing, Jobs sons all died. When God restored him, he had seven sons and three daughters. He gave the daughters an inheritance among their brothers. Would Job's grand sons (The daughter's sons) have been "sons of Job" by lineage? Or does verse 16 indicate that the daughters sons were not considered his sons?
טו וְלֹא נִמְצָא נָשִׁים יָפוֹת, כִּבְנוֹת אִיּוֹב--בְּכָל-הָאָרֶץ; וַיִּתֵּן לָהֶם אֲבִיהֶם נַחֲלָה, בְּתוֹךְ אֲחֵיהֶם.
טז וַיְחִי אִיּוֹב אַחֲרֵי-זֹאת, מֵאָה וְאַרְבָּעִים שָׁנָה; וירא (וַיִּרְאֶה), אֶת-בָּנָיו וְאֶת-בְּנֵי בָנָיו--אַרְבָּעָה, דֹּרוֹת.
