NIV
They have spoken mere words of the lips, swearing falsely in making covenants; therefore judgment springs up like hemlock [or other poisonous plants] in the furrows of the field.
AMP
They have spoken words, swearing falsely in making a covenant: thus judgment springeth up as hemlock in the furrows of the field.
