John 11:50 Meaning

48If we let him thus alone, all men will believe on him: and the Romans shall come and take away both our place and nation.

49And one of them, named Caiaphas, being the high priest that same year, said unto them, Ye know nothing at all,

50Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not.

51And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;

52And not for that nation only, but that also he should gather together in one the children of God that were scattered abroad.
