Our choices can cause irreparable harm to others, including the next generation. That’s a key lesson from the Torah reading אמר Emor (“say,” Leviticus 21-24).
The Holy One of Israel loves mercy more than rote obedience, and He loathes hypocrisy. God looks at our conduct, as well as the heart behind our actions. We can fool those around us, we might even fool ourselves, but we can’t fool God.
