Portions: Deuteronomy 15-20

However, there should be no poor among you,
for in the land the Lord your God 
is giving you to possess as your inheritance,
He will richly bless you,
if only you fully obey the Lord your God
and are careful to follow all these commands
I am giving you today.
(Deuteronomy 15:4-5)

Observe the month of Abib
and celebrate the Passover of the Lord your God,
because in the month of Abib
He brought you out of Egypt by night.
(Deuteronomy 16:1)

When you enter the land the Lord your God is giving you
and have taken possession of it and settled in it,
and you say, "Let us set a king over us
like all the nations around us,"
be sure to appoint over you
the king the Lord your God chooses.
He must be from among your own brothers.
Do not place a foreigner over you,
one who is not a brother Israelite.
The king, moreover,
must not acquire great numbers of horses for himself
or make the people return to Egypt to get more of them,
for the Lord has told you,
"You are not to go back that way again."
He must not take many wives,
or his heart will be led astray.
He must not accumulate large amounts of silver and gold.
When he takes the throne of his kingdom,
he is to write for himself on a scroll
a copy of this law,
taken from that of the priests, who are Levites.
It is to be with him,
and he is to read it all the days of his life
so that he may learn to revere the Lord his God
and follow carefully all the words of this law
and these decrees
and not consider himself better than his brothers
and turn from the law to the right or to the left.
Then he and his descendants will reign a long time
over his kingdom in Israel.
(Deuteronomy 17:14-20)

When you enter the land the Lord your God is giving you,
do not learn to imitate
the detestable ways of the nations there.
Let no one be found among you
who sacrifices his son or daughter in the fire,
who practices divination or sorcery,
interprets omens, engages in witchcraft,
or casts spells, or who is a medium or spiritist
or who consults the dead.
Anyone who does these things is detestable to the Lord,
and because of these detestable practices
the Lord your God will drive out those nations before you.
You must be blameless before the Lord your God.
(Deuteronomy 18:9-13)

You must purge the evil from among you.
(Deuteronomy 19:19)

When you lay siege to a city for a long time,
fighting against it to capture it,
do not destroy its trees by putting an ax to them,
because you can eat their fruit.
Do not cut them down.
Are the trees of the field people,
that you should besiege them?
(Deuteronomy 20:19)
