Rabbi Yaron Reuven brings a Torah proof from Parashat Nasso. For nearly 900 years that the First and Second Beit HaMikdash stood, a woman suspected of adultery was taken to the Kohanim to go through to ordeal of the Bitter Waters. If she was guilty of cheating on her husband, she would turn green, explode and die. And during this time, nobody came forward to deny the miracle of the Bitter Waters. This is just one of many proofs that the Torah is from God and not a man made book like the other religions of the world.
