Leviticus 24:17 - Ellicott's Commentary On The Whole Bible

And he that killeth a man. — The enactment that in case of blaspheming no difference is to be made between a non-Israelite and Israelite, is now followed by other laws respecting murder and personal injury which have been given before (Exodus 21:12, &c.), but which are here repeated in order to show that, like blasphemy, they apply alike to Gentile and Jew. It may also be that the repetition here of the law of murder is designed to draw a distinction between the judicial sentence of death carried out by the community, and the illegal taking away of life by individuals.
