Exodus 4:8 Meaning and Commentary

Exodus 4:8

And it shall come to pass, if they will not believe thee
Will not give credit to the commission he had from God, but question the truth of it: neither hearken to the voice of the first sign;
which miracle wrought, spoke plain enough that he that wrought it, or for whose sake it was wrought, must be one come from God, or such a miracle would never be wrought by him or for him; but should any of the Israelites be still incredulous, it is supposed, that they will believe the voice of the latter sign;
which had a voice in it commanding belief that he was a messenger of God; the first sign respects his rod, the other his hand.

Exodus 4:8 In-Context

6 The LORD said to him, "Put your hand inside your shirt." So Moses did this, and when he took his hand out, it had a skin disease. It looked as [flaky as] snow.

7 "Now put your hand back inside your shirt," the LORD said. Moses put it back, and when he took it out this time, it was healthy again like the rest of his body.

8 [Then the LORD said,] "If they won't believe you or pay attention to the first miraculous sign, they may believe the second.

9 But if they won't believe these two miraculous signs or listen to you, take some water from the Nile River and pour it on the ground. The water you take from the Nile will turn into blood on the ground."

10 Moses said to the LORD, "Please, Lord, I'm not a good speaker. I've never been a good speaker, and I'm not now, even though you've spoken to me. I speak slowly, and I become tongue-tied easily."
