'Falsehood' in the Bible

When I would have healed Israel, then the iniquity of Ephraim was discovered, and the wickedness of Samaria: for they commit falsehood; and the thief cometh in, and the troop of robbers spoileth without.

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.

Ephraim compasseth me about with falsehood, and the house of Israel with deceit; but Judah yet ruleth with God, and is faithful with the Holy One.
