Blood curse

God pronounced a blood curse on the royal family of Judah in Jeremiah 22:

Is this man Coniah a despised, broken pot,
a vessel no one cares for?
Why are he and his children hurled and cast
into a land that they do not know?
O land, land, land,
hear the word of the Lord!
Thus says the Lord:
"Write this man down as childless,
a man who shall not succeed in his days,
for none of his offspring shall succeed
in sitting on the throne of David
and ruling again in Judah.

This is the same Coniah (Jechoniah) that shows up in Matthew's genealogy of Christ:

and Josiah the father of Jechoniah and his brothers, at the time of the deportation to Babylon...and Jacob the father of Joseph the husband of Mary, of whom Jesus was born, who is called Christ.

Of course, Joseph is only Jesus' legal father, but still the inheritance comes down through the father and Joseph's line has been cursed.  In step the daughters of Zelophehad.

The names of his daughters were: Mahlah, Noah, Hoglah, Milcah, and Tirzah. And they stood before Moses and before Eleazar the priest and before the chiefs and all the congregation, at the entrance of the tent of meeting, saying, "Our father died in the wilderness. He was not among the company of those who gathered themselves together against the Lord in the company of Korah, but died for his own sin. And he had no sons. Why should the name of our father be taken away from his clan because he had no son? Give to us a possession among our father's brothers."

Moses brought their case before the Lord. And the Lord said to Moses,"The daughters of Zelophehad are right. You shall give them possession of an inheritance among their father's brothers and transfer the inheritance of their father to them. And you shall speak to the people of Israel, saying, 'If a man dies and has no son, then you shall transfer his inheritance to his daughter.

and in Numbers 36:

And every daughter who possesses an inheritance in any tribe of the people of Israel shall be wife to one of the clan of the tribe of her father, so that every one of the people of Israel may possess the inheritance of his fathers.

Mary is an heiress to the line of David also, but through Nathan, Solomon's brother, thus bypassing the blood curse and allowing Gabriel to say to Mary,

"Do not be afraid, Mary, for you have found favor with God. And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end."

Fruitless trees

Jesus rode into Jerusalem as the King

And many spread their cloaks on the road, and others spread leafy branches that they had cut from the fields. And those who went before and those who followed were shouting, “Hosanna! Blessed is he who comes in the name of the Lord! Blessed is the coming kingdom of our father David! Hosanna in the highest!” (Mark 11:8-10)

On the following day, when they came from Bethany, he was hungry. And seeing in the distance a fig tree in leaf, he went to see if he could find anything on it. When he came to it, he found nothing but leaves, for it was not the season for figs. And he said to it, “May no one ever eat fruit from you again.” And his disciples heard it. (12-14)

There is a link between the leafy branches that the people cut and spread and the leafy branches of the fig tree. The people look like healthy trees, full of leaves, and from a distance seeming to carry much fruit with their crying out of praise to the King. But, as with the fig tree, the people are nothing but leaves. They put on a great show of religion, but have no faith. So, they were cursed. Within a week the crowd rejected the very Messiah they had blessed.

He ties it together the next day.

As they passed by in the morning, they saw the fig tree withered away to its roots. And Peter remembered and said to him, “Rabbi, look! The fig tree that you cursed has withered.” And Jesus answered them, “Have faith in God. Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. (20-23)

The fig tree is "this mountain", the mountain on which Jerusalem stood, which He told his disciples to pray would "be taken up and thrown into the sea".

"O Jerusalem, Jerusalem, the city that kills the prophets and stones those who are sent to it! How often would I have gathered your children together as a hen gathers her brood under her wings, and you would not! See, your house is left to you desolate." (Mat 23:37)

Because Jerusalem "would not", what they had trusted in - the oracles, commandments, temple, heritage - would be taken away. Because they were a fruitless show of leaves,

Therefore I tell you, the kingdom of God will be taken away from you and given to a people producing its fruits. (Mat 21:43)

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."
