I don’t think Jesus’ New Covenant followers are required to follow any of the commandments in the old covenant. His followers are expected to obey the all-encompassing command in the new covenant that Jesus Himself instituted at the Last Supper. This new covenant replaced the old one. This new covenant established by Jesus retired the old one that God established with the nation of Israel.
And His new commandment was a replacement for all of the old commandments, just as His new covenant replaced the old covenant. His new commandment wasn’t an additional commandment to the already existing list of commandments. He didn’t introduce it as “here’s the 614th commandment.” He introduced it as “By this all people will know that you are my disciples.” While the old covenant, and all of the rules and regulations that came with it, was significant in God’s creation of the nation of Israel, and it helped separate them from their neighbors, and it gave them some moral guidelines — Jesus’ death and resurrection marked the end of the covenant that God made with Israel, and all of the rules and regulations that came with it.
