There's this strange passage in Exodus in which Moses begs to see God's glory, but God interprets this as meaning his backside.* God warns Moses that he cannot reveal his face to a mortal, for doing so would be deadly. Instead, God proposes to pass by Moses while using his divine hand to block himself from Moses' view, then reveal himself—his backside—to Moses while retreating (Exodus 33:18-23).
