Romans 10:2

2 For I bear them record that they have a zeal of God, but not according to knowledge.

Ver. 2. They have a zeal of God ] So had those two Rabbis, David Rubenita and Shelomoh Molchu, that set upon the Emperor Charles v. to persuade him to Judaism, and were therefore put to a cruel death, A. D. 1530. (Alsted. Chron.) So had Latimer before his conversion: I was as obstinate a Papist, saith he, as any was in England: insomuch that when I should be made Bachelor in Divinity, my whole oration went against Philip Melancthon and his opinions, &c. Being a priest, and using to say mass, he thought he had never sufficiently mingled his massing wine with water: and moreover that he should never be dammed, if he were once a professed friar; with various such superstitious fantasies. (Acts and Mon.) Zeal without knowledge is as wild fire in a fool’s hand; it is like the devil in the demoniac, that casts him sometimes into the fire and sometimes into the water.
