And Moses spake before the Lord
Who appeared in a visible form, and had spoke to him with an
articulate voice, and before whom Moses stood, and made the
following reply:
saying, behold, the children of Israel have not hearkened
unto me;
even though he brought a comfortable message to them from the
Lord, and delivered many gracious promises of his to them,
assuring them of deliverance out of Egypt, and of their
possession of the land of Canaan:
how then shall Pharaoh hear me?
making a demand upon him to part with a people, from whose labour
he receives so much advantage, and has such an addition to his
revenues, and who is a mighty king, and haughty monarch. And this
is further enforced from his own weakness and unfitness to speak
to Pharaoh:
who [am] of uncircumcised lips?
had an impediment in his speech, could not speak freely and
readily, but with difficulty; perhaps stammered, and so uttered
superfluous syllables, repeated them before he could fully
pronounce what he aimed at; or in other words, he was not
eloquent, which was his old objection, and had been fully
answered before: and by this it appears that there was no
alteration in the speech of Moses since God spoke with him at
Mount Horeb. Some think Moses expected to have had this
impediment removed, and tacitly hints at it here, not being so
well satisfied with Aaron's being joined with him as his mouth
and spokesman, which seemed to carry in it some reflection upon
him.
