Amos 8:5
saying, "When will the New Moon be over that we may sell grain, and the Sabbath be ended that we may market wheat?"-- skimping the measure, boosting the price and cheating with dishonest scales,
It all starts with a cheating intention and ends with a cheating attitude. It develops into a cheating culture and a very organised cheating group of people. Thats what it is!
Habakkuk 2:9-11
"Woe to him who builds his realm by unjust gain to set his nest on high, to escape the clutches of ruin! You have plotted the ruin of many peoples, shaming your own house and forfeiting your life. The stones of the wall will cry out, and the beams of the woodwork will echo it.
