10 Never forget the day when you stood before the Lord your God at Mount Sinai,*4:10 Hebrew Horeb, another name for Sinai; also in 4:15. where he told me, ‘Summon the people before me, and I will personally instruct them. Then they will learn to fear me as long as they live, and they will teach their children to fear me also.’
