“I (G-d) will raise them up a prophet from among their brethren, like unto you (Moses); and I will put My words in his mouth, and he shall speak unto them all that I shall command him” (Deut. 18: 18)
The Torah claims that G-d revealed Himself to the entire Israelite people at Mt. Sinai. The commandments, or guiding instructions of the Torah, can never make complete sense from a human perspective, because the very definition of revelation is knowledge bestowed from a Divine perspective.
To give a simple metaphor, revelation is like Waze. You are driving down route 83, and you wonder which is the quickest route to your destination. Is there a traffic jam ahead? Should you get off at the next exit and take an alternative route? Or take your chances with the traffic lights on the main thoroughfare? There is really no way for you to know; you cannot possibly see the next two miles of roadway. But the Waze satellite hovering overhead sees everything. From its perspective, all the highways and traffic patterns are perfectly visible. So you turn on your Waze, and you hear the clear message: “Traffic jam on route 83 between Kilmer and Havington, exit at route 144.” Even the most deluxe, state-of-the-art automobile can never know what Waze knows. That is revelation.
