He rent his clothes; either in detestation of his blasphemy, in giving God's perfections to him; or rather, for grief arising from a suspicion and fear that the Syrian made this only a pretence for the war which he designed against him. I God, to kill and to make alive? he expresseth it thus, because leprosy is a kind or degree of death, Numbers 12:12, and he thought it as impossible to cure it as to raise the dead. See how he seeketh a quarrel against me, for not doing what he requires, which he knows impossible for me to do.
