tn The Hebrew word נְפִילִים (néfilim) is simply transliterated here, because the meaning of the term is uncertain. According to the text, the Nephilim became mighty warriors and gained great fame in the antediluvian world. The text may imply they were the offspring of the sexual union of the “sons of God” and the “daughters of humankind” (v. 2), but it stops short of saying this in a direct manner. The Nephilim are mentioned in the OT only here and in Num 13:33, where it is stated that they were giants (thus KJV, TEV, NLT “giants” here). The narrator observes that the Anakites of Canaan were descendants of the Nephilim. Certainly these later Anakite Nephilim could not be descendants of the antediluvian Nephilim (see also the following note on the word “this”).

tn This observation is parenthetical, explaining that there were Nephilim even after the flood. If all humankind, with the exception of Noah and his family, died in the flood, it is difficult to understand how the postdiluvian Nephilim could be related to the antediluvian Nephilim or how the Anakites of Canaan could be their descendants (see Num 13:33). It is likely that the term Nephilim refers generally to “giants” (see HALOT 709 s.v. נְפִילִים) without implying any ethnic connection between the antediluvian and postdiluvian varieties.

tn Heb “were entering to,” referring euphemistically to sexual intercourse here. The Hebrew imperfect verbal form draws attention to the ongoing nature of such sexual unions during the time before the flood.

tn Heb “and they gave birth to them.” The masculine plural suffix “them” refers to the “sons of God,” to whom the “daughters of humankind” bore children. After the Qal form of the verb יָלָד (yalad, “to give birth”) the preposition לְ (lé, “to”) introduces the father of the child(ren). See Gen 16:1, 15; 17:19, 21; 21:2–3, 9; 22:23; 24:24, 47; 25:2, etc.

tn The parenthetical/explanatory clause uses the word הַגִּבֹּרִים (haggibborim) to describe these Nephilim. The word means “warriors; mighty men; heroes.” The appositional statement further explains that they were “men of renown.” The text refers to superhuman beings who held the world in their power and who lived on in ancient lore outside the Bible. See E. A. Speiser, Genesis (AB), 45–46; C. Westermann, Genesis, 1:379–80; and Anne D. Kilmer, “The Mesopotamian Counterparts of the Biblical Nephilim,” Perspectives on Language and Text, 39–43.

tn Heb “men of name” (i.e., famous men).
