Exodus 6:9

When Moses communicated this solemn assurance of God to the people, they did not listen to him רוּה מּקּצר, lit., "for shortness of breath;" not "from impatience" (like קצר־רוּח, Pro 14:29, in contrast to אפּים ארך), but from anguish, inward pressure, which prevents a man from breathing properly. Thus the early belief of the Israelites was changed into the despondency of unbelief through the increase of their oppression. This result also produced despondency in Moses' mind, so that he once more declined the commission, which followed the promise, viz., to go to Pharaoh and demand that he would let Israel go out of his land (Exo 6:11). If the children of Israel would not listen to him, how should Pharaoh hear him, especially as he was uncircumcised in the lips (Exo 6:12)? שׁפתים ערל is one whose lips are, as it were, covered with a foreskin, so that he cannot easily bring out his words; in meaning the same as "heavy of mouth" in Exo 4:10. The reply of God to this objection is given in Exo 7:1-5. For, before the historian gives the decisive answer of Jehovah which removed all further hesitation on the part of Moses, and completed his mission and that of Aaron to Pharaoh, he considers it advisable to introduce the genealogy of the two men of God, for the purpose of showing clearly their genealogical relation to the people of Israel.

Much ado there was to bring Moses to his work, and when the ice was broken, some difficulty having occurred in carrying it on, there was no less ado to put him forward in it. Witness this chapter, in which, I. God satisfies Moses himself in an answer to his complaints in the close of the foregoing chapter (Exo 6:1). II. He gives him fuller instructions than had yet been given him what to say to the children of Israel, for their satisfaction (Exo 6:2-8), but to little purpose (Exo 6:9). III. He sends him again to Pharaoh (Exo 6:10, Exo 6:11). But Moses objects against that (Exo 6:12), upon which a very strict charge is given to him and his brother to execute their commission with vigour (Exo 6:13). IV. Here is an abstract of the genealogy of the tribes of Reuben and Simeon, to introduce that of Levi, that the pedigree of Moses and Aaron might be cleared (Exo 6:14-25), and then the chapter concludes with a repetition of so much of the preceding story as was necessary to make way for the following chapter.

6:9 The crisis deepened as the people refused to listen to the reaffirmation of the promises. They had not anticipated that their initial faith would produce greater problems for them.
