Therefore, I'll give their wives to others, and their fields to new owners. Indeed, from the least important to the most important, they're all greedy for dishonest gain. From prophet to priest, they all act deceitfully.

"Beware of your neighbors, and don't trust any of your relatives. For all of your relatives act deceitfully, and every friend goes around as a slanderer.

And they act deceitfully every one with his neighbour, and speak not the truth: they teach their tongue to speak falsehood, they weary themselves with perverse dealing.

“Their tongue is a murderous arrow;It speaks deceit;With his mouth one speaks peace to his neighbor,But in his heart he lays traps and waits in ambush for him.

You, O Lord are [uncompromisingly] righteous and consistently just when I plead my case with You;Yet let me discuss issues of justice with You:Why has the way of the wicked prospered?Why are those who deal in treachery (deceit) at ease and thriving?

For ye have dealt deceitfully against your own souls; for ye sent me unto Jehovah your God, saying, Pray for us unto Jehovah our God; and according unto all that Jehovah our God shall say, so declare unto us, and we will do it:

Cursed be he that doeth the work of the LORD deceitfully, and cursed be he that keepeth back his sword from blood.
