'Worthless' in the Bible

A worthless person, a wicked man,Is one who walks with a perverse (corrupt, vulgar) mouth.

He who tills his land will have plenty of bread,But he who follows worthless things lacks common sense and good judgment.

A worthless man devises and digs up evil,And the words on his lips are like a scorching fire.

A wicked and worthless witness mocks justice,And the mouth of the wicked spreads iniquity.

“It is [almost] worthless, it is [almost] worthless,” says the buyer [as he negotiates the price];But when he goes his way, then he boasts [about his bargain].

He who cultivates his land will have plenty of bread,But he who follows worthless people and frivolous pursuits will have plenty of poverty.
