"But to do justly and to love mercy....." Micah 6:8

"The balances in which we weigh our own and other men's characters, are they quite accurate? Do we not turn our own ounces of goodness into pounds, and other persons' bushels of excellence into pecks?" -Charles Spurgeon 

 "We must see to this matter, lest we get reported to the court above for unjust dealing. Those weights with which we measure our doctrinal belief, are they quite fair? The doctrines of grace should have the same weight with us as the precepts of the word, no more and no less; but it is to be feared that with many one scale or the other is unfairly weighted." Charles Spurgeon 

Leviticus 19:36 

"Just balances, just weights, a just ephah, and a just hin, shall ye have: I am the Lord your God, which brought you out of the land of Egypt."

Proverbs 11:1 A false balance is abomination to the Lord: but a just weight is his delight.
