He saw one of them being mistreated by an Egyptian, so he went to his help and took revenge on the Egyptian by killing him. (
When Moses had grown up, he went out to visit his people, the Hebrews, and he saw how they were forced to do hard labor. He even saw an Egyptian kill a Hebrew, one of Moses' own people.
Moses looked all around, and when he saw that no one was watching, he killed the Egyptian and hid his body in the sand.
“When Moses was forty years old, he decided to find out how his fellow Israelites were being treated.
He thought that his own people would understand that God was going to use him to set them free, but they did not understand.)
‘Do you want to kill me, just as you killed that Egyptian yesterday?’
