Proverbs 11:1 proclaims: “A false balance is an abomination to Yahweh, but a just weight is His delight.” This verse reminds us that God is concerned with more than just our “religious” life. He wants us to be honest in everything we do — even in the business world.
The “false balance” and “weight” referred to here are the measures used in commerce, to weight out grain or some other product which is being sold. It would not be uncommon for traders to “fudge” a bit on the weights, in order to make a better bargain for themselves. Some of them may have even been Israelites, who just thought that doing so was “just businesss” or “no big deal.” But here God makes it clear that the way you do business is His concern. Cheating in business is not a little thing to Him; in fact it says here that it is “an abomination”!
The principle here applies not only to those with literal “scales”, of course, but to business of ALL kinds. Don’t cheat your customers — even a “little”. And don’t cheat your employer, either, if you work for someone. Don’t “fudge” on mileage reimbursements and other expenses. Be absolutely honest in all of these things, even when they seem to be “no big deal” to others in the business. We need to remember that in God’s eyes, matters of integrity are never “little.” Integrity is always a BIG deal!

How one lives his or her life regarding personal honesty in all things says a lot about one’s inner spiritual condition and the reality of one’s profession. Do we really put God first or has the love of money snuck back in to a place it shouldn’t occupy? We need to remember that “godliness with contentment is great gain” (1 Timothy 6:6) and that we also need to keep the words of Hebrews 13:5 in mind: “Keep your life free from love of money, and be content with what you have, for he has said, “I will never leave you nor forsake you.”
