SEV Biblia, Chapter 6:12
Y respondió Moisés delante del SEÑOR, diciendo: He aquí, los hijos de Israel no me escuchan, ¿cómo pues me escuchará el Faraón, mayormente siendo yo incircunciso de labios?
Clarke's Bible Commentary - Exodus 6:12
Verse 12. Uncircumcised lips?] The word lr[ aral, which we translate uncircumcised, seems to signify any thing exuberant or superfluous. Had not Moses been remarkable for his excellent beauty, I should have thought the passage might be rendered protuberant lips; but as this sense cannot be admitted for the above reason, the word must refer to some natural impediment in his speech; and probably means a want of distinct and ready utterance, either occasioned by some defect in the organs of speech, or impaired knowledge of the Egyptian language after an absence of forty years. See note on "chap. iv. 10".
Matthew Henry Commentary
Verses 10-13 - The faith of Moses was so feeble that he could scarcely be kept to his work. Ready obedience is always according to the strength of our faith Though our weaknesses ought to humble us, yet they ought not to discourage us from doing our best in any service we have to do for God When Moses repeats his baffled arguments, he is argued with no longer but God gives him and Aaron a charge, both to the children of Israel and to Pharaoh. God's authority is sufficient to answer all objections and binds all to obey, without murmuring or disputing, Php 2:14.
