'Heads' in the Bible

And [when] they resisted and reviled [him], he shook out [his] clothes [and] said to them, "Your blood [be] on your [own] heads! I [am] guiltless! From now on I will go to the Gentiles!"

Take these [men] [and] purify yourself along with them and {pay their expenses} so that they can shave [their] heads, and everyone will know that [the things] which they had been informed about you are nothing, but you yourself also agree with observing the law.
