Go with these men to the Temple and ritually purify yourself along with them. Then, when it is time for them to offer the sacrifices for that ritual, pay for what they offer as sacrifices. After that, they can shave their heads to show that they have done what they promised to do. And when people see you in the courts of the Temple with those men, they will know that what they have been told {what people have told them} about you is not true. Instead, all of them will know that you obey all our Jewish laws and rituals.
