What does the phrase, "you are not allowed to hide yourself" mean?

Answer From The Annual Reading Schedule - Week 46 Notes For Deuteronomy: This phrase is found in Deuteronomy 22:3. It means don't act like something never happened and ignore what the command of Yahweh is. Yahweh knows what's going on and He can see our hearts. We need to be aware of this and doing our best to do what is right even when we're alone.
