God. Elohim. If Genesis 9:18-27 are Jehovistic (Tuch, Bleek, Colenso, et alii), why Elohim? Is this a proof that the Jehovistic document was revised by the Elohistic author, as the presence of Jehovah in any so-called Elohistic section is regarded as an interpolation by the supplementer? To obviate this inference Davidson assigns Genesis 9:20-27 to his redactor. But the change of name is sufficiently explained when we remember that "Jehovah, as such, never was the God of Japheth's descendants, and that the expression would have been as manifestly improper if applied to him as it is in its proper place applied to Shem". Shall enlarge Japheth. יַפְתְּ לְיֶפֶת; literally, shall enlarge or make room for the one that spreads abroad; or, "may God concede an ample space to Japheth" (Gesenius). "Wide let God make it for Japheth" (Keil). "God give enlargement to Japheth" (Lange). So LXX; Vulgate, Chaldee, Syriac, Arabic. The words form a paronomasia, both the verb and the noun being connected with the root פָתָה, to spread abroad; Hiph; to cause to lie open, hence to make room for,—and refer to the widespread diffusion and remarkable prosperity of the Japhetic nations. The familiar interpretation which renders "God will persuade Japheth, the persuadable," i.e. incline his heart by the gospel so that he may dwell in the tents of Shem (Junins, Vatablus, Calvin, Willet, Ainsworth), is discredited by the facts
And Noah lived after the flood three hundred and fifty years. I.e. to the fifty-eighth year of the life of Abram, and was thus in all probability a witness of the building of the tower of Babel, and of the consequent dispersion of mankind. And all the days of Noah were nine hundred and fifty years: and he died. Tuch, Bleek, and Colenso connect these verses with Genesis 9:17, as the proper continuation of the Elohist's work.
