Later on Moses saw a Egypt guard beeting a hebrew old women so moses got involved and helped the old women
Moses then killed a egyption guard and ran into the desert and got married and had a son
Joshua later went out of egypt to find moses to tell him all the hard labor the egyptions are putting on the task masters to put on the Jews.
G-d called on moses saying your the man who will help me lead my people out of slavery and into the land where i swore to your fathers Abraham Isaac Jacob that you will dwell in this land and so shall your seed and your seeds seed.
So the king hardend his hard and g-d put plegus on egypt 10 of them to be real
and the final plegue was G-d came to earth with his angels of death and doom and he killed all the first born of egypt starting with the servends that were not Jews to the Kings own son.
