What does Exodus 4:10 mean?
Moses' first resistance to the Lord's call (Exodus 3:10) was doubt in his own importance (Exodus 3:11). His next concern was about proving that he'd really spoken with God (Exodus 3:13; 4:1). Now, God has provided three miraculous signs which Moses can use against skepticism (Exodus 4:8–9).Now, Moses expresses more doubts about himself. He claims to be a poor speaker. There is no suggestion in Scripture that he had an actual speech impediment—though that is possible. It probably means that Moses didn't think of himself as a powerful orator or an eloquent man. He was certainly educated (Exodus 2:10). Later generations would applaud his speaking (Acts 7:22). This may also have been an excuse inspired by fear or intimidation over his mission. Whether he lacked confidence or ability, Moses expresses this to the Lord.
God responds by telling Moses not to worry about his own power. God's presence and guidance will be enough (Exodus 4:11–12).
Exodus 4:10–17 records Moses resisting God's call by pointing out his poor speaking ability. When God says He will endow Moses with the right words at the right time, Moses is still overwhelmed and skeptical. Though angry at the lack of faith, God responds by appointing Moses' brother, Aaron, to be the public spokesman, bringing words from God through Moses.
While speaking with God in the form of a supernaturally burning bush, Moses expresses a lack of confidence. God gives Moses several miraculous signs so he can prove the source of his message. Moses is still unsure because of his poor speech. Though irritated, God appoints Moses' brother, Aaron, to be the spokesman while Moses relays the words of God. Moses returns to Egypt. Along the way, he nearly dies due to God's anger over some issue related to circumci-sion. After meeting his brother, Moses convinces the elders of Israel that his mission is genuine.
