What is the ninth commandment?

298 Less than a minute

Of the ten commandments, the ninth commandment says, “You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his manservant, or his maidservant, or his ox, or his ass, or anything that is your neighbor’s.” The ninth commandment demands that:-

We should never do anything to weaken or damage our marriage commitments through my obsession with someone else
Similarly, we should not do anything to weaken or damage someone else’s marriage
We must not say or do anything that will make a mockery of the sacred promises of marriage

This commandment encourages the purification of our hearts through prayer, the practice of chastity and purity of intention and of vision.
