Deuteronomy 17:10 Meaning and Commentary

Deuteronomy 17:10

And thou shalt do according to the sentence which they of that
place which the Lord shall choose shall show thee
The judges of the inferior courts were to return and proceed on the difficult case according to the judgment of the great court at Jerusalem, and follow the directions and instructions they should give them:

and thou shalt observe to do according to all that they inform thee;
not only observe and take notice of what they say, but put it in practice, and not in some things and some circumstances only, but in all and everything they should give them information about relating to the case in question.

Deuteronomy 17:10 In-Context

8 “Suppose a case arises in a local court that is too hard for you to decide—for instance, whether someone is guilty of murder or only of manslaughter, or a difficult lawsuit, or a case involving different kinds of assault. Take such legal cases to the place the LORD your God will choose,

9 and present them to the Levitical priests or the judge on duty at that time. They will hear the case and declare the verdict.

10 You must carry out the verdict they announce and the sentence they prescribe at the place the LORD chooses. You must do exactly what they say.

11 After they have interpreted the law and declared their verdict, the sentence they impose must be fully executed; do not modify it in any way.

12 Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must die. In this way you will purge the evil from Israel.
