This explanation of Holy Scripture will show you that the apostle Paul encourages/instructs both Jewish and Gentile believers in Messiah (Christ), to observe the Law of Moses (Torah).
This will be achieved by showing you that the apostle Paul brought and or met with believers who were originally born as Greeks into the temple of G-d to do a commandment (ritual) known as the Nazirite vow, a cleansing statute from the Law of Moses.
From this we also see that both Jews and Gentiles who believe in Messiah (Christ), are deemed Israelites – as the penalty for bringing a non-Jew into the Temple was death in ancient times.
