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
In a country where life is simple, this is much easier than in our part of the world. However, even there the servant must watch closely or he or she will fail in service. A devoted servant will been keenly aware of their master's will, even when the only indication is a lifted eyebrow or a small motion of the eyes.
What a beautiful illustration of the relationship which should exist between the Lord and His servants!
