John Trapp on Isaiah 63:8

Ver. 8. For he ſaid, Surely they are my people, children that will not lye] q. d. I preſume they will not, it were a foul ſhame for them if they ſhould deceive my expectation, deale diſloyally, ſhew themſelves deceitful in the Covenant. The Officers of Merindol in France anſwered the Popiſh Biſhop that moved them to abjure, that they marvelled much that he would offer to perſwade them to lye to God and the world. And albeit that all men by nature are lyars, yet they had learned by the Word of God, that they ought diligently to take heed of lying in any matter, be it never ſo ſmall; Alſo that they ought diligently to take heed that their children did not accuſtome or uſe themſelves to lye, and therefore puniſh them very ſharply when they took them with any lye,Act. & Mon. 866. even as if they had committed a robbery; for the devil is a lyar, &c. Here the Biſhop roſe up in a great anger, and ſo departed.
