Deuteronomy 4:6-9 NIV
Observe them carefully, for this will show your wisdom and understanding to the nations, who will hear about all these decrees and say, “Surely this great nation is a wise and understanding people.” What other nation is so great as to have their gods near them the way the LORD our God is near us whenever we pray to him? And what other nation is so great as to have such righteous decrees and laws as this body of laws I am setting before you today?
Only be careful, and watch yourselves closely so that you do not forget the things your eyes have seen or let them fade from your heart as long as you live. Teach them to your children and to their children after them.
NIV: New International Version
