What does Exodus 6:28 mean?
The final verses of this chapter reiterate Moses' doubts about his role and the Lord's demand that Moses bring all the required messages to Pharaoh (Exodus 7:1–2). Moses has already shown a lack of self-confidence (Exodus 3:11; 4:10, 13). Recently, he referred to himself as someone with "uncircumcised lips" (Exodus 6:12). This may be Moses' protest about his speaking skills or a claim that he's not holy enough for the job.At the burning bush (Exodus 3:4–6), Moses said he was unable to speak well (Exodus 4:10). The Lord assured him that He would "be with your mouth and teach you what to speak" (Exodus 4:12), but Moses asked God to send someone else (Exodus 4:13). God still sent Moses, but He sent Aaron with him (Exodus 4:14–16, 27). Moses would lead the people from Egypt as their spiritual guide and source of authority. But Aaron would serve as God's mouthpiece before Pharaoh (Exodus 7:1–7). This special arrangement would later continue in a different way as Aaron would serve as the first high priest of Israel while Moses led the nation (Exodus 29:9).
