1 tn Heb “And to Shem was born.”
2 tn Or “whose older brother was Japheth.” Some translations render Japheth as the older brother, understanding the adjective הַגָּדוֹל (haggadol, “older”) as modifying Japheth. However, in Hebrew when a masculine singular definite attributive adjective follows the sequence masculine singular construct noun + proper name, the adjective invariably modifies the noun in construct, not the proper name. Such is the case here. See Deut 11:7; Judg 1:13; 2:7; 3:9; 9:5; 2 Kgs 15:35; 2 Chr 27:3; Neh 3:30; Jer 13:9; 36:10; Ezek 10:19; 11:1.
3 tn The expression “the earth was divided” may refer to dividing the land with canals, but more likely it anticipates the division of languages at Babel (Gen 11). The verb פָּלָג (palag, “separate, divide”) is used in Ps 55:9 for a division of languages.
