Chp. 3 verses 19 - 22 Chp. 4 verses 1 - 9: Hashem tells Moshe that Pharaoh will not agree to let the people go until He smites him with all His wonders. Also that they would leave Egypt with gold, silver, and clothing that they would borrow from the Egyptians. Chp. 4, Moshe says to G-d that the people would not believe that Hashem had appeared to him. Then G-d gives him three signs, the snake, leprosy, and blood, to present before the people so that they would know that he was the true redeemer and the time for the redemption was now.
