The Lord saith. These self-styled prophets find their counterpart in many preachers today who propound false doctrines that they passionately assert are supported by a “Thus saith the Lord.” No matter how earnestly a doctrine may be propounded, no matter how impressive the titles held by its proponents, it should find no place of acceptance in the believer’s creed unless the Lord has actually spoken it. However plausible human theories may appear to be, it should never be forgotten that they lack divine authority.
Others. This word is supplied. The clause may be translated “they hoped to confirm the word.” By the fulfillment of the predicted event they hoped to substantiate their reliability. They may have hoped that God would honor their self-appointed mission and cause their presumptuous utterances to materialize.
