So shalt thou put away the guilt of innocent blood from among you, when thou shalt do that which is right in the sight of the LORD.

And thou shalt be free from the innocent's blood, that was shed, when thou shalt have done what the Lord hath commanded thee.

So shalt thou put away innocent blood from thy midst, when thou shalt do what is right in the eyes of Jehovah.

So shalt thou remove the guilt of innocent blood from among you, when thou shalt do that which is right in the sight of the LORD.

and thou dost put away the innocent blood out of thy midst, for thou dost that which is right in the eyes of Jehovah.

So you will take away the crime of a death without cause from among you, when you do what is right in the eyes of the Lord.

Then you will be free from the blood that was shed against the innocent, when you will have done as the Lord has instructed you.

Tu autem auferes sanguinem innocentem e medio tui, quum feceris quod rectum est in oculis Jehovae.

So shalt thou put away the guilt of innocent blood from among you,.... Which otherwise, the person not being found out, and brought to just punishment for it, would devolve upon the whole. Aben Ezra interprets it the punishment of innocent blood, which, by the above method being taken, would not be inflicted on them:
when thou shalt do that which is right in the sight of the Lord; as it was to observe this law concerning the beheading of the heifer, with all the rites and ceremonies belonging to it here enjoined; as well as every other command, statute, and ordinance of the Lord, which are all right to be done, Psalm 19:8.

In this way Israel was to wipe away the innocent blood (the bloodshed) from its midst (cf. Numbers 35:33). If the murderer were discovered afterwards, of course the punishment of death which had been inflicted vicariously upon the animal, simply because the criminal himself could not be found, would still fall upon him.
