Jewish, belonging to Judah. Ioudaios. Salvation is from the Jews. God chose a people to bring the Messiah into the world. His choice of Israel was for the benefit of all nations.

Circumcision, the covenant cut. Peritomē. Abraham received it as a sign of the righteousness he had by faith before the knife ever fell. The true circumcision is of the heart. Let the inner life match the outward sign.

Slave, servant, bondservant. Doulos. Paul a servant of Jesus Christ. The highest title Paul claimed was slave of Christ. Belonging completely to Jesus is the greatest freedom.

unrestrained (to go at pleasure), i.e. (as a citizen) not a slave (whether freeborn or manumitted), or (genitive case) exempt (from obligation or liability)
