John Trapp on Isaiah 7:10

Ver. 10. Moreover the Lord ſpake again unto Ahaz] Wicked though he were, and under the power of unbelief, yet he ſhall ſee that he hath to do with a very gracious and long-ſuffering God, who, by a wonderful condeſcenſion, will needs give him a ſign; Inauditum vero, dari ſignum incredulo. Chriſt would not ſo far gratifie the unbelieving Phariſees, but calleth them an evil and baſtardly brood for ſeeking a ſign from Heaven, Mat. 12.39.
