'Falsehood' in the Bible

'When I give healing to Israel, Then revealed is the iniquity of Ephraim, And the wickedness of Samaria, For they have wrought falsehood, And a thief doth come in, Stript off hath a troop in the street,

They have spoken words, To swear falsehood in making a covenant, And flourished as a poisonous herb hath judgment, on the furrows of a field.
