Behold, as the eyes of servants look unto the hand of their masters, and as the eyes of a maiden unto the hand of her mistress; so our eyes wait upon the LORD our God, until that he have mercy upon us.  Psalms 123:2

.....there is no reason why we should be ashamed of, or offended at, being compared to slaves, provided God is our defender, and takes our lives under his guardianship; God, I say, who purposely disarms us and strips us of all worldly aid, that we may learn to rely upon his grace, and to be contented with it alone.  It having been anciently a capital crime for bondmen to carry a sword or any other weapon about them, and as they were exposed to injuries of every description, their masters were wont to defend them with so much the more spirit, when anyone causelessly did them violence.  Nor can it be doubted that God, when he sees us placing an exclusive dependence upon his protection, and renouncing all confidence in our own resources, will, as our defender, encounter and shield us from all the molestation that shall be offered to us.
