I had listened to one of Dr. Scott Hahn’s talks in the Our Father’s Plan series. Here are some notes I made from talk number 5. They might help answer your question. You can download all the talks from the link below. Listen to talk number 5 in particular.

Notes-
Deuteronomy is not merely a repetition of the law, it is as the name implies, a second law.
Deuteros = second
nomos = (word for) law
40 years earlier, at the covenant at Sinia, God came in thunder and lightning and fire. Deuteronomy is made, without any kind of manifestation of God’s presence.
The Deuteronomy covenant, is a long oration given by Moses on the plains of Moab. This covenant, is made by Moses on God’s behalf, instead of God himself.
God the Father has to now take on the role of a
master, whereas Israel is now like a slave.
In Deuteronomy, there are some distinctive laws.
Deut 29:1
In Deuteronomy, you see certain
concessions being made, although
not directly by God. God allows Moses to become the primary law-giver.
The wise and prudent law giver has to assess the moral condition of the people, so that he doesn’t erect a legal standard impossibly high. - St. Thomas Aquinas
So Moses starts to
tolerate certain evils that were not tolerated before. Deut 24:1-4,
Moses (not God) allows divorce (you know what Jesus said). You can charge interest from Gentiles.
So Deuteronomy is isolationist, it isolates Israel from the Gentiles. God sees that Israel is more tempted to be like the nations than the nations are drawn to be like Israel.
You also see permanent slavery instituted. You also see Moses allowing polygamy and also marrying foreign wives. Harem warfare – slaughter Caananite men and women. This is not what God says. This is what Moses** concedes**!
Deut 12:15 – another distinctive law.
The central sanctuary – the focal point of all of ancient Israel’s subsequent history.
Only in Deut 17, does Moses give permission to have a secular king. It can’t be a foreigner.
Deut 27-34 – an ominous note. It’s no longer, “if” you disobey. Israel comes under a curse. The curses are elaborated in excruciating detail in chapter 28. In chapter 29, Moses tells the reason why the curses are going to fall. The Israelites don’t have a heart for God, because they have not sought it! They don’t have in themselves to keep the law and attain holiness.
When you are exiled and call to God, God will circumcize your hearts.
In Deut 10 – circumcize your own hearts.
In Deut 30 – (at that time) I will circumcize your hearts.
The law was given to Israel by God, so that they would seek grace. The law was given so that grace might be sought. Then grace is given, so that the law might finally be obeyed. - St. Augustine.
When Paul says the law is dismissed, he is referring to those that came after the golden calf and Baal of Peor. Those are the laws which the council in Acts 15 dispensed Christians from.
Ezekiel 20:18-26
Deuteronomy is a self-retiring covenant that makes way for the new covenant.
Grace does not make law keeping easy. Grace makes it possible!
