Exodus 4:8

8 The Lord said, If they shall not believe to thee, neither shall hear the word of the former sign, either miracle, they shall believe to the word of the sign following; (And the Lord said, If they do not believe thee, nor accept the proof of the first sign, or the first miracle, then they may believe the proof of the sign that followeth;)

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 And the Lord said again to Moses, Put thine hand into thy bosom; and when he had put it into his bosom, he brought forth it leprous, at the likeness of snow. (And the Lord said to Moses, Put thy hand inside thy cloak; and after he had put it inside his cloak, when he took it out again, he brought it forth leprous, and as white as snow.)

7 The Lord said, Again draw thine hand into thy bosom; Moses again drew (in) his hand, and brought it forth again, and it was like to the tother flesh. (And the Lord said, Put thy hand inside thy cloak again; and Moses put his hand inside his cloak, and when he took it out again, once more it was like his other flesh.)

8 The Lord said, If they shall not believe to thee, neither shall hear the word of the former sign, either miracle, they shall believe to the word of the sign following; (And the Lord said, If they do not believe thee, nor accept the proof of the first sign, or the first miracle, then they may believe the proof of the sign that followeth;)

9 that if they believe not to these two signs, neither hear thy voice, take thou water of the flood, and shedded out it on the dry land, and whatever thing thou shalt draw up of the flood, it shall be turned into blood. (but if they do not believe these two signs, nor will listen to thy voice, then take some water from the River, and pour it out onto the dry land; and whatever water thou shalt draw up out of the River, it shall be turned into blood, when it falleth onto the ground.)

10 Moses said, Lord, I beseech (thee), I am not eloquent, that is, a fair speaker, from yesterday and the third day ago; and since thou hast spoken to thy servant, I am of more hindered, and of slower tongue.
