After He says above, You did not want or delight in sacrifices and offerings, whole burnt offerings and sin offerings (which are offered according to the law),

You did not delight
in whole burnt offerings and sin offerings.

and if the household is worthy, let your peace be on it. But if it is unworthy, let your peace return to you.

Don’t assume that I came to bring peace on the earth. I did not come to bring peace, but a sword.

If a son of peace is there, your peace will rest on him; but if not, it will return to you.
