1 Corinthians 7:10-11
10 And unto the married I command, yet not I, but the Lord, Let not the wife depart from her husband:
τοῖς δὲ γεγαμηκόσιν παραγγέλλω οὐκ ἐγὼ ἀλλ' ὁ κύριος γυναῖκα ἀπὸ ἀνδρὸς μὴ χωρισθῆναι
11 But and if she depart, let her remain unmarried or be reconciled to her husband: and let not the husband put away his wife.
ἐὰν δὲ καὶ χωρισθῇ μενέτω ἄγαμος ἢ τῷ ἀνδρὶ καταλλαγήτω καὶ ἄνδρα γυναῖκα μὴ ἀφιέναι
