Parallel
Numbers 8:17
Brenton's English Septuagint · Berean Standard Bible
For every first-born among the children of Israel [is] mine, whether of man or beast: in the day in which I smote every first-born in the land of Egypt, I sanctified them to myself.
For every firstborn male in Israel is Mine, both man and beast. I set them apart for Myself on the day I struck down all the firstborn in the land of Egypt.
