Again, a new King (Pharaoh), took the throne of Egypt, and this King was even worse to the Children of Israel.

HaShem knew that it was time to get the Children of Israel out of Egypt. [It was told to Abraham that his children would serve 400 years as slaves to another people. So it really didn't have anything to do with the Egyptians.]

Moshe worked as a shepherd for his father-in-law. While tending the sheep, he came to HaShem's mountain, Mount Horeb. This is the same mountain where Abraham had brought Isaac, and the same mountain where, one day, the Beit Hamikdash would stand.

On this mountain, Mount Horeb, HaShem appeared to Moshe in the "heart of a fire, in the middle of a thorn-bush. Moshe saw the bush and the fire, and noticed that the bush itself was not burning. He decided to come closer to the bush.

As Moshe got closer to the bush, HaShem called out to him: "Moshe, Moshe." Moshe answered, and HaShem told him not to get closer, and to take off his shoes, because he was standing on holy ground.

HaShem then told Moshe that HaShem was the G-D of Abraham and of Isaac and of Jacob.

HaShem said that it was time for HaShem to bring the Children of Israel out of Egypt. HaShem told Moshe that Moshe had to go to Egypt to bring out HaShem's people, the Children of Israel.
