Psalms 123:2

2. As the eyes of servants, etc. The allusion is to the custom of dispensing favours, giving protection, or issuing orders, by the motion of the hand. In India, a man in trouble says, “I will look to the hand of my friend.” Roberts. “In Egypt everything is done with the greatest decency and the most profound silence, the slaves or servants standing at the bottom of the room, with their hands joined before them, watching with the utmost attention every motion of their master, who commands them by signs.” Pococke. Ladies are waited on, even at the least wink of their eye or motion of their fingers. This custom prevails all over the East, and this language of signs is frequently alluded to in the prophets. In the present case the hand is looked to for protection; and the waiting attitude is one of submission, trust, and readiness to obey orders, or to receive the token of deliverance.
