Keep him alive, Heb. quicken him, i.e. revive and restore him. Either he will preserve him from trouble; or if God see trouble necessary or fit for him, and therefore suffer him to fall into it, he will raise him out of it. Unto the will of his enemies, i.e. to destruction, which they earnestly desire and endeavour to procure.
