Galatians 3:28
“There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus.”
Paul's Letter to the Galatians is addressed to early Christian communities in Galatia (modern-day Turkey), likely written in the mid-1st century CE. He's passionately defending his gospel of salvation by faith in Christ, not by adherence to the Jewish law, especially concerning the inclusion of non-Jewish (Gentile) believers.
