'Cheat' in the Bible

Everyone must be on his guard around his friends. He must not even trust any of his relatives. For every one of them will find some way to cheat him. And all of his friends will tell lies about him.

The businessmen love to cheat; they use dishonest scales.

You say, "When will the new moon festival be over, so we can sell grain? When will the Sabbath end, so we can open up the grain bins? We're eager to sell less for a higher price, and to cheat the buyer with rigged scales!
