Clement of Alexandria, on Heb 13:4

“Marriage honourable in all, and the bed undefiled. For fornicators and adulterers God will judge.”

“But rather, he says, "Follow peace with all men, and holiness, without which no man shall see the Lord: looking diligently, lest there be any fornicator or profane person, as Esau, who for one morsel surrendered his birth-right; and lest any root of bitterness springing up trouble you, and thereby many be defiled." And then, as putting the finishing stroke to the question about marriage, he adds: "Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge."”
