Deuteronomy 25:13

Divers weights. “Two kinds of weights” (RSV), a lighter weight used in selling and a larger one in purchasing. Literally, “a stone and a stone, large and small.” Ancient Hebrew weights were usually made of stone. Amos 8:5 indicates that this particular type of dishonesty was not uncommon among the Jews. Note the statement about different weights in Proverbs 20:23, as an “abomination” to Jehovah, whereas just weights are approved by the Lord (Proverbs 16:11). The prophet Micah makes a similar statement on God’s displeasure with unjust weights (Micah 6:11). God designs that among His people principles of justice and equity shall prevail. Those who serve God will not cheat their fellow men (see 1 John 4:20).
