I've addressed these matters several times. Your position is not based on Scripture.
Not based on scripture? Then what sign is it based on?
Signs as that seen are for those who have no faith coming from prophecy they must walk by what they see, as those who do wrestle against flesh and blood . Prophecy the mind of God for those who do walk by that faith comes from hearing God....as it is written. The Israelites knew the promise to Abraham that he would deliver a new people out of bondage (400 years) to represent our born again salvation was soon coming, By Moses and Aaron. Levites to set up a kingdom of priests.
If they did not believe the first two sign. I will destroy the first born

(purple in parenthesis) my addition as a commentary.
Exodus 4:1- 9 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice: for they will say, The Lord hath not appeared unto thee. And the Lord said unto him, What is that in thine hand? And he said, A rod. And he said, Cast it on the ground. And he cast it on the ground, and it became a serpent;
(the power of the letter of the law) and Moses fled from before it.
And the Lord said unto Moses, Put forth thine hand, and take
it by the tail.
(the rod of rebellion)And he put forth his hand, and caught it, and it became a
rod in his hand:
That they may believe that the Lord God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob,
hath appeared unto thee. And the Lord said
furthermore unto him, Put now
thine hand into thy bosom. And he put his hand into his bosom: and
when he took it out, behold, his hand was leprous as snow.
(dead in trespasses and sins ) And he said, Put thine hand into thy bosom again. And
he put his hand into his bosom again; and plucked it out of his bosom, and, behold, it was turned again as his other flesh.(born again)
And it shall come to pass, if they will not believe thee, neither hearken to the voice of the
first sign, that they will believe the
voice of the
latter sign. (Twice dead) And it shall come to pass, if they will not believe also these
two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river
shall become blood upon the dry land.
(And pollute the whole land of the Pharaoh with dead spiritless blood )
