Exodus 6:9-13

And Moses spake so unto the children of Israel: but they hearkened not unto Moses for anguish of spirit, and for cruel bondage.

Moses spake. The increased severities inflicted on the Israelites seem to have so entirely crushed their spirits, as well as irritated them, that they refused to listen to any more communications from the two divinely-commissioned ambassadors (Exodus 14:12). Even the faith of Moses himself was faltering; and he would have abandoned the enterprise in despair, had he not received a positive command from God to revisit the people without delay, and at the same time renew their demand on the king in a more decisive and peremptory tone.

Verse 12. How then shall Pharaoh hear me, who am of uncircumcised lips? A metaphorical expression among the Hebrews, who, taught to look on the circumcision of any part as denoting perfection, signified its deficiency or unsuitableness by uncircumcision. The words here express how painfully Moses felt his want of utterance or persuasive oratory. He seems to have fallen into the same deep despondency as his brethren, and to be shrinking with nervous timidity from a difficult, if not desperate cause. If he had succeeded so ill with the people, whose dearest interests were all involved, what better hope could he entertain of his making more impression on the heart of a king elated with pride and strong in the possession of absolute power? How strikingly was the indulgent forbearance of God displayed toward His people amid all their backwardness to hail his announcement of approaching deliverance! No perverse complaints or careless indifference on their part retarded the development of His gracious purposes. On the contrary, here, as generally, the course of His providence is slow in the infliction of judgments, while it moves more quickly, as it were, when misery is to be relieved or benefits conferred.
