[6:11] 1 tn The form וִישַׁלַּח (vishallakh) is the Piel imperfect or jussive with a sequential vav; following an imperative it gives the imperative’s purpose and intended result. They are to speak to Pharaoh, and (so that as a result) he will release Israel. After the command to speak, however, the second clause also indirectly states the content of the speech (cf. Exod 11:2; 14:2, 15; 25:2; Lev 16:2; 22:2). As the next verse shows, Moses doubts that what he says will have the intended effect.
[6:12] 2 tn Heb “And Moses spoke before.”
[6:12] 3 sn This analogy is an example of a qal wahomer comparison. It is an argument by inference from the light (qal) to the heavy (homer), from the simple to the more difficult. If the Israelites, who are Yahwists, would not listen to him, it is highly unlikely Pharaoh would.
[6:12] 4 tn The final clause begins with a disjunctive vav (ו), a vav on a nonverb form – here a pronoun. It introduces a circumstantial causal clause.
[6:12] 5 tn Heb “and [since] I am of uncircumcised lips.” The “lips” represent his speech (metonymy of cause). The term “uncircumcised” makes a comparison between his speech and that which Israel perceived as unacceptable, unprepared, foreign, and of no use to God. The heart is described this way when it is impervious to good impressions (Lev 26:41; Jer 9:26) and the ear when it hears imperfectly (Jer 6:10). Moses has here returned to his earlier claim – he does not speak well enough to be doing this.
