From Joshua 14:
I was forty years old when Moses the servant of the Lord sent me from Kadesh Barnea to explore the land. And I brought him back a report according to my convictions, 8 but my fellow Israelites who went up with me made the hearts of the people melt in fear. I, however, followed the Lord my God wholeheartedly.
From Deuteronomy 25:
13 Do not have two differing weights in your bag—one heavy, one light. 14 Do not have two differing measures in your house—one large, one small. 15 You must have accurate and honest weights and measures, so that you may live long in the land the Lord your God is giving you. 16 For the Lord your God detests anyone who does these things, anyone who deals dishonestly.
