From this and other like expressions of Saul s, some gather that he was exceeding prone to the vice of swearing and cursing. Thou shalt surely die: strange perverseness! He who was so indulgent as to spare wicked Agag, 1Sa 15, is now so severe as to destroy his own worthy son: he that could easily dispense with God's righteous and reasonable command, will not bear the violation of his own rash and foolish command; because his own authority and power is concerned in this, and only God's in the other.
