How do people learn?
Now, Israel, what does the LORD your God require of you except to revere him, to obey all his commandments, to love him, to serve him with all your mind and being, and to keep the Lord’s commandments and statutes that I am giving you today for your own good? –Deuteronomy 10:12-13
I think it might be…
Revere the LORD your God, serve him, be loyal to him and take oaths only in his name. –Deuteronomy 10:20
Repetition.
You must love the LORD your God and do what he requires; keep his statutes, ordinances, and commandments at all times. –Deuteronomy 11:1
There are many other verses in this book where you can hear the same thing. I’d bore you with a list but if you are that interested you will read my favorite Old Testament book and find them for yourself.
