New Defender's Study Bible Notes
7:12 not the Lord. Again Paul is claiming, not disclaiming, divine authority for his teaching. In fact, he is even boldly superseding a command given by God through Ezra to the Jews. After returning from their captivity in Babylon, the Jews had taken wives from the unbelieving people of the land, and God told them: “Separate yourselves from the people of the land, and from the strange [i.e., foreign] wives” (Ezra 10:11). In the Christian context, however, a Christian is commanded not to divorce a non-Christian spouse, as long as the latter is willing to remain in the marriage.
