'Deceitful' in the Bible

The wicked man earns deceptive wages,But he who sows righteousness and lives his life with integrity will have a true reward [that is both permanent and satisfying].

A truthful witness saves lives,But he who speaks lies is treacherous.

Differing weights are detestable and offensive to the Lord,And fraudulent scales are not good.

Do not desire his delicacies,For it is deceptive food [offered to you with questionable motives].

Faithful are the wounds of a friend [who corrects out of love and concern],But the kisses of an enemy are deceitful [because they serve his hidden agenda].
