Whosoever therefore would have safety and deliverance, must seek and expect it only from the watchful eye and almighty hand and mercy of God. Them that fear him; these are the chief objects of his care and favour. Them that hope in his mercies; that place their hope, and trust, and happiness not in any creature, but only in God, and in his mercy and blessings. The conjunction and order of these two qualifications of the person whom God careth for is observable here, they must be such as fear God, and so make conscience of keeping his commands, Ecclesiastes 12:13, and then they may and must hope in or rely upon his mercy for their safety and happiness.
