As that 400 years was coming to a close,

God prepared Moses

to lead the children of Israel out of their bondage. The purpose was to “bring forth my people, the children of Israel, out of Egypt.” Ex 3:10. However it was not be anything like Moses had started out 40 years earlier. It seems Moses was so completely stung by his earlier experience that he no longer had any thought of himself as able to deliver Israel.

Still, God personally called Moses

at Mount Sinai. God says He, the Lord, will do it.

“I have come down to deliver them …”
Ex 3:8

God says He will send Moses to Pharaoh that he might bring forth God’s people, Ex 3:10. Moses is now 80 years old, not an eloquent man, herding sheep way off in boonies. He painfully feels his limitations, and is no longer aggressive but very humble in attitude. Moses replies.

… “Who am I, that I should go to Pharaoh, and that I should bring forth the children of Israel out of Egypt?”
Ex 3:11

God explains how to talk to the Israelites and assures Moses they will listen to him, Ex 3:18

Further, God explains that Pharaoh
will NOT listen.

God says He will strike Egypt.

“I will put forth my hand and strike Egypt with all my wonders which I will do in the midst of it, and after that he will let you go.”
Ex 3:20

Moses still protests his inability. He says they will not listen to him, or believe that Yahweh has spoken to him. God gives Moses a series of signs to demonstrate God being with him. The rod turning into a serpent, his hand becoming leprous, and turning the water of the Nile to blood,

Likewise the prophet like Moses (Deut 18:15), came
with powerful signs from God.

In fact, Jesus Himself was a sign.

“and Simeon blessed them, and said to Mary, his mother, “Behold, this child is set for the falling and the rising of many in Israel, and for a sign which is spoken against.”
Lk 2:34

Jesus works indeed were signs of His divinity, and His approval by God, and many were believing.

“Now when he was in Jerusalem at the Passover, during the feast, many believed in his name, observing his signs which he did.”
Jn 2:23

Some of the Sanhedrin, the ruling council of the Jews, were also convinced, and Nicodemus came to Jesus at night to discuss these things, saying,

… “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do, unless God is with him.”
Jn 3:2

The ultimate sign of His Sonship was His
resurrection from the dead.

This focus on spectacular feats irritated Jesus.

“For as Jonah was three days and three nights in the belly of the whale, so will the Son of Man be three days and three nights in the heart of the earth.”
Mtt 12:40

All to lead God’s people out of slavery to sin, in a wicked world.
