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.
