'Year' in the Bible

But a certain one of them, Caiaphas, being high priest that year, said to them, Ye know nothing

But this he did not say of himself; but, being high priest that year, prophesied that Jesus was going to die for the nation;

and they led him away to Annas first; for he was father-in-law to Caiaphas, who was high priest that year.
