The second possiblility is that the Law and Judges were only for Israel.
This does not seem to be true. God also intended the law for the nations around Israel. He expected them to see the wisdom of Israel’s law and copy them for themselves.
Observe them carefully, for this will show your wisdom and understanding to the nations, who will hear about all these decrees and say, "Surely this great nation is a wise and understanding people." And what other nation is so great as to have such righteous decrees and laws as this body of laws I am setting before you today? (Deut 4:6-8).The tabernacle and sacrifices were just for Israel, but the civil law was for all nations.
