Why did Mosheh (Moses) teach the children of Yisra'el (Israel) to do the laws and right-rulings (judgments)? What can we learn from this?

Answer From The Annual Reading Schedule - Week 42 Notes For Deuteronomy: To live – and to go in and possess the land (Deuteronomy 4:1). We learn from this that breaking the law is what leads to death. This lines up with 1 John 3:4 which says sin is the transgression of the law and other verses like ones in Romans teaching that sin leads to death.
