Gen 4:26: "then it was begun to call on the name of the Lord"

Says Seth's son is אֱנוֹשׁ. Then אָז הוּחַל לִקְרֹא בְּשֵׁם יְהוָה. הוּחַל is a Hophal (OSHB), impersonal: "it was begun." BDB, under the verb "pollute, defile, profane" (Hiphil also "begin"), gives this verse as "then it was begun (= men began) to call on the name of" the Lord. The phrase is used of Abram at an altar, וַיִּקְרָא בְּשֵׁם יְהוָה (12:8; also 13:4; 21:33; 26:25), and of the Lord proclaiming his name (Exod 34:5). Swete has οὗτος ἤλπισεν ἐπικαλεῖσθαι, "this one hoped to call on" (see var.Gen.4.26.began-hoped).

Uncertain What began; no lean is taken here. (1) Public worship in Seth's line; grounds: the phrase at altars (12:8; 26:25). (2) Proclaiming, or calling oneself by, the name; grounds: Exod 34:5. (3) A beginning of profaning, from the other sense of the verb, a later Jewish reading. Objection: the phrase elsewhere is worship. (4) The Greek's "he hoped," of Enosh.

Uncertain Exod 6:3: "by My name the Lord I did not make Myself known to them." (a) Exodus means the name's character known in deed, not the word; objection: "known" is said of the name. (b) The narrator uses the name from his own later standpoint; objection: 4:26 says the calling began then. (c) Different strands date the name differently: Skinner (p. 127) reads 4:26 as one strand's view, unlike Exod 3:13–15 and 6:3, which "base the name on express revelation"; objection: this rests on a source division (see note.historical.Gen.2.4-Gen.2.25.two-accounts-question). No lean is taken among them.
