1 sn This means “later” in relation to the births of the three sons (Jerahmeel, Ram and Caleb) mentioned in v. 9.
2 tn Heb “Hezron went to.”
3 tn Heb “he took,” referring to taking in marriage.
4 tn Heb “And after the death of Hezron in Caleb Ephrathah, and the wife of Hezron, Abijah, and she bore to him Ashhur the father of Tekoa.” Perhaps one could translate: “After Hezron died in Caleb Ephrathah, Abijah, Hezron’s wife, bore to him Ashhur, the father of Tekoa” (cf. NASB, NIV, NRSV). In this case the text suggests that Abijah was born after his father’s death. Because of the awkward syntax and the odd appearance of “Caleb Ephrathah” as a place name, some prefer to emend the text. Some alter בְּכָלֵב אֶפְרָתָה (bÿkhalev ’efratah, “in Caleb Ephrathah”) to בָּא כָלֵב אֶפְרָתָה (bo’ khalev ’efratah, “Caleb had sexual relations with Ephrath”) and then change אֲבִיָּה (’aviyyah, “Abijah”) to אָבִיהוּ (’avihu, “his father”). This results in the following translation: “And after Hezron’s death, Caleb had sexual relations with Ephrath, his father Hezron’s wife, and she bore to him Ashhur the father of Tekoa” (cf. NAB). This would mean that Caleb’s second wife Ephrath had actually been his late father’s wife (probably Caleb’s stepmother). Perhaps the text was subsequently altered because Caleb’s actions appeared improper in light of the injunctions in Lev 18:8; 20:11; Deut 22:30; 27:20 (which probably refer, however, to a son having sexual relations with his stepmother while his father is still alive).
