John 12:20-24

Now among those who went up to worship at the Feast were some Greeks. These came to Philip, who was from Bethsaida in Galilee, and they made this request, Sir, we desire to see Jesus. Philip came and told Andrew; then Andrew and Philip together [went] and told Jesus. And Jesus answered them, The time has come for the Son of Man to be glorified and exalted. I assure you, most solemnly I tell you, Unless a grain of wheat falls into the earth and dies, it remains [just one grain; it never becomes more but lives] by itself alone. But if it dies, it produces many others and yields a rich harvest.
