Salmi 10:13

Wherefore doth the wicked contemn God? he hath said in his heart, Thou wilt not require [it].

Ver. 13. Wherefore doth the wicked contemn God?] q.d. It is time for thee, Lord, to arise and bestir thyself; for otherwise what will become of thy great name? The saints cannot endure that God should be slighted.

He hath said in his heart] Salmi 10:3,4. This sticks in David's stomach, and draws this prayer from him, who was now blessedly blown up with a holy zeal for God; as was also good Zuinglius, when he said, In aliis mansnetus ero, in blasphemiis in Christum non ita, In other matters I can be mild and patient, but not so in case of blasphemy against Christ.
