If anyone eats a sacred offering in error, he must add a fifth to its value and give the sacred offering to the priest.
KJV
And if a man eat [of] the holy thing unwittingly, then he shall put the fifth [part] thereof unto it, and shall give [it] unto the priest with the holy thing.
ASV
And if a man eat of the holy thing unwittingly, then he shall put the fifth part thereof unto it, and shall give unto the priest the holy thing.
