Proverbs 16:11 A just weight and balance are the LORD’S: all the weights of the bag are his work. 

‘A just weight and balance are the LORD’s.’ Just weights and honest scales are ordained by God (11:1; Lev. 19:36).

‘All the weights of the bag’ refers to the standard weights kept in the sanctuary, used as the national benchmark to ensure fairness in commerce. It may also refer to the weights merchants carried in their pouches or belts, used to weigh money in trade. These tools were to reflect integrity and truth in every transaction.

Deceit is fundamentally falsehood (Ps. 119:118). Scripture teaches that deceit originates in the human heart (Jer. 17:9; Mark 7:22; Rom. 3:13). God utterly abhors it (Ps. 5:6) and commands His people to avoid it entirely (Job 27:4; 31:5; Pro. 24:28; 1Pet. 3:10). God’s faithful people are to be free from deceit (Ps. 24:4; Isa. 53:9; Zeph. 3:13; 1Pet. 2:22; Rev. 14:5). We are called to reject deceit (Ps. 43:1; 72:14; 101:7; 120:2; Eph. 5:6; Col. 2:8) and put it away completely (2Cor. 4:2; 1Thess. 2:3; 1Pet. 2:1). Scripture consistently links deceit with the wicked (Ps. 10:7; 35:20; 36:3; 38:12; Pro. 11:18; 12:5; 20:17; Jer. 9:5; 37:9; 2Tim. 3:13), with false teachers (Job 15:35; Pro. 12:17; Jer. 14:14; 23:26; Rom. 16:18; 2Cor. 11:13; Eph. 4:14; 2Thess. 2:1-17; 2Pet. 2:13; 2 John 1:7), and warns of its destructive consequences (Ps. 10:7; 24:4-5; 32:2; 55:23; Pro. 14:8, 25; 26:24; 27:6; Jer. 8:5; 9:6). God requires truth in the inward parts, not just outward behaviour, but inward integrity (Ps. 51:6). His desire is to renew and perfect our inner being daily through the gospel (2Cor. 4:16). This is the true test of character (Ps. 15:1-5): living with honesty, justice, and sincerity in all dealings.
