What does Mosheh (Moses) say would happen to them if they broke this agreement and what does this mean?
Answer From The Annual Reading Schedule - Week 40 Notes For Numbers: Their sin would find them out (Numbers 32:23). This seems to mean that they won't be able to escape the calamity or judgment that Yahweh would permit to happen to them because of their sin if they sinned in that way. This phrase gives me the impression of, "Don't think you can just get away with it – Yahweh sees everything." or, "A man reaps what he sows." (similar to Galatians 6:7).
