Parallel
Numbers 8:7
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
And thus shalt thou do unto them, to cleanse them: Sprinkle water of purifying upon them, and let them shave (note: Heb. let them cause a razor to pass over, etc) all their flesh, and let them wash their clothes, and so make themselves clean.
This is what you must do to cleanse them: Sprinkle them with the water of purification. Have them shave their whole bodies and wash their clothes, and so purify themselves.
