Leviticus 24 chiasm

Leviticus 24:13-23 forms a chiasm
I've modified this a little from the original posting. The "A"s didn't quite line up as well as I would like.

A. Then the Lord spoke to Moses, saying, "Bring out of the camp the one who cursed, and let all who heard him lay their hands on his head, and let all the congregation stone him.

B. And speak to the people of Israel, saying, Whoever curses his God shall bear his sin. Whoever blasphemes the name of the Lord shall surely be put to death. All the congregation shall stone him.

C.  The sojourner as well as the native, when he blasphemes the Name, shall be put to death.

D. "Whoever takes a human life shall surely be put to death.

E. Whoever takes an animal's life shall make it good, life for life.

F. If anyone injures his neighbor, as he has done it shall be done to him,

F'. fracture for fracture, eye for eye, tooth for tooth; whatever injury he has given a person shall be given to him.

E'. Whoever kills an animal shall make it good,

D'. and whoever kills a person shall be put to death.

C'. You shall have the same rule for the sojourner and for the native,

B'. for I am the Lord your God."

A'. So Moses spoke to the people of Israel, and they brought out of the camp the one who had cursed and stoned him with stones. Thus the people of Israel did as the Lord commanded Moses.

John 6 chiasm

John 6:53-57
A. Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves.
B. He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day.
C. For My flesh is true food, and My blood is true drink.
B'. He who eats My flesh and drinks My blood abides in Me, and I in him.
A'. As the living Father sent Me, and I live because of the Father, so he who eats Me, he also shall live because of Me.

Does it make sense if it is restructured helically?
A. Eating the flesh and blood of Jesus is the only source of life
A' What is more, He lives in the Father and those that eat His body live in Him
B. Whoever eats from Him has eternal life and resurrection
B' What is more, it is a shared communion
C. His flesh and blood are true food and drink

Again?
A/A' Life proceeds from the Father, through the Son, to those in communion
B/B' What is more, this communion is an intimate sharing of the very life of God
C What is more, His life is our only sustenance

Matthew 15 chiasm

Mathew 15:1-20 makes a fairly robust chiasm.

A. Then Pharisees and scribes came to Jesus from Jerusalem
and said, "Why do your disciples break the tradition of the
elders? For they do not wash their hands when they eat."

B. He answered them, "And why do you break the
commandment of God for the sake of your tradition?
For God commanded, 'Honor your father and your mother,'
and, 'Whoever reviles father or mother must surely die.'
But you say, 'If anyone tells his father or his mother,
"What you would have gained from me is given to God," he
need not honor his father.' So for the sake of your
tradition you have made void the word of God. You hypocrites!

C. Well did Isaiah prophesy of you, when he said:
"'This people honors me with their lips,
but their heart is far from me;
in vain do they worship me,
teaching as doctrines the commandments of men.'"

D. And he called the people to him and said to them,
"Hear and understand: it is not what goes into the
mouth that defiles a person, but what comes out of
the mouth; this defiles a person."

E. Then the disciples came and said to him, "Do you
know that the Pharisees were offended when they
heard this saying?"

E'. He answered, "Every plant that my heavenly Father
has not planted will be rooted up. Let them alone;
they are blind guides. And if the blind lead the
blind, both will fall into a pit."

D'. But Peter said to him, "Explain the parable to us."
And he said, "Are you also still without understanding?
Do you not see that whatever goes into the mouth passes
into the stomach and is expelled?

C'. But what comes out of the mouth proceeds from the heart,
and this defiles a person.

B'. For out of the heart come evil thoughts, murder, adultery,
sexual immorality, theft, false witness, slander. These
are what defile a person.

A'. But to eat with unwashed hands does not defile anyone."
