Jeremiah 21:31-34 (ESV)
31 31 “Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah, 32 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. 33 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. 34 And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”
John 12:20-33 (ESV)
12 20 Now among those who went up to worship at the feast were some Greeks. 21 So these came to Philip, who was from Bethsaida in Galilee, and asked him, “Sir, we wish to see Jesus.” 22 Philip went and told Andrew; Andrew and Philip went and told Jesus. 23 And Jesus answered them, “The hour has come for the Son of Man to be glorified. 24 Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit. 25 Whoever loves his life loses it, and whoever hates his life in this world will keep it for eternal life. 26 If anyone serves me, he must follow me; and where I am, there will my servant be also. If anyone serves me, the Father will honour him.
27 “Now is my soul troubled. And what shall I say? ‘Father, save me from this hour’? But for this purpose I have come to this hour. 28 Father, glorify your name.” Then a voice came from heaven: “I have glorified it, and I will glorify it again.” 29 The crowd that stood there and heard it said that it had thundered. Others said, “An angel has spoken to him.” 30 Jesus answered, “This voice has come for your sake, not mine. 31 Now is the judgment of this world; now will the ruler of this world be cast out. 32 And I, when I am lifted up from the earth, will draw all people to myself.” 33 He said this to show by what kind of death he was going to die.
