Barnes' Notes
Moved with envy - That is, dissatisfied with the favor which their father Jacob showed Joseph, and envious at the dreams which indicated that he was to be raised to remarkable honor above his parents and brethren, Genesis 37:3-11.
Sold Joseph into Egypt - Sold him, that he might be taken to Egypt. This was done at the suggestion of "Judah," who advised it that Joseph might not be put to death by his brethren, Genesis 37:28. It is possible that Stephen, by this fact, might have designed to prepare the way for a severe rebuke of the Jews for having dealt in a similar manner with their Messiah.
But God was with him - God protected him, and overruled all these wicked doings, so that he was raised to extraordinary honors.
