John Calvin Commentary Leviticus 19:29

"Profane not thy daughter, to make her a harlot; lest the land fall to whoredom, and the land become full of wickedness." — Leviticus 19:29 (ASV)

This passage more clearly proves that all unlicensed connections⁶⁴ were always unlawful in God’s sight.

It is a tame and forced interpretation to apply what is said here to spiritual fornication. Those who suppose that only public brothels are forbidden also restrict the law too much. God, rather, gives a general injunction that parents should preserve their daughters by means of a pure and chaste education.

But even if we admit that nothing else is prohibited but that parents should be the panders of their daughters, we still gather from the word pollute⁶⁵ (for some render the word חלל, chalal, too tamely to make common) that they are contaminated by their whoredom. The reason given abundantly confirms that all whoredom is hateful to God: lest the land fall to whoredom, He says, and the land become full of wickedness.

It is plain that adultery is not in question here; rather, God declares it criminal if a man and woman have connection out of wedlock. Consequently, the people are taught in the Seventh Commandment to beware of all unchastity.
