John 1:29-37

29 The next day he saw Jesus coming toward him, and said, “Behold, the Lamb of God, who takes away the sin of the world!

30 This is he of whom I said, ‘After me comes a man who ranks before me, because he was before me.’

31 I myself did not know him, but for this purpose I came baptizing with water, that he might be revealed to Israel.”

32 And John bore witness: “I saw the Spirit descend from heaven like a dove, and it remained on him.

33 I myself did not know him, but he who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain, this is he who baptizes with the Holy Spirit.’

34 And I have seen and have borne witness that this is the Son of God.”

35 The next day again John was standing with two of his disciples,

36 and he looked at Jesus as he walked by and said, “Behold, the Lamb of God!”

37 The two disciples heard him say this, and they followed Jesus.

Romans 5:12

Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned—

Romans 6:23

For the wages of sin is death…

Romans 3:23

for all have sinned and fall short of the glory of God,

Hebrews 9:22

… and without the shedding of blood there is no forgiveness of sins.

1 Corinthians 5:7

Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed.

1 Peter 1:18-19

18 knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold,

19 but with the precious blood of Christ, like that of a lamb without blemish or spot.

Mark 14:22-24

22 And as they were eating, he took bread, and after blessing it broke it and gave it to them, and said, “Take; this is my body.”

23 And he took a cup, and when he had given thanks he gave it to them, and they all drank of it.

24 And he said to them, “This is my blood of the covenant, which is poured out for many.

Revelation 5:6

And between the throne and the four living creatures and among the elders I saw a Lamb standing, as though it had been slain…

Revelation 5:9-13

9 And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation,

10 and you have made them a kingdom and priests to our God, and they shall reign on the earth.”

11 Then I looked, and I heard around the throne and the living creatures and the elders the voice of many angels, numbering myriads of myriads and thousands of thousands,

12 saying with a loud voice, “Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!”

13 And I heard every creature in heaven and on earth and under the earth and in the sea, and all that is in them, saying, “To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever!”
