so our eyes [wait] upon the Lord our God; look unto him for direction in his service. Saints are servants, not of sin, nor of Satan, nor of men, but of the Lord; and not on the foot of creation only, but of redemption, and are made so by the grace of God; and they are willing to work, and are desirous to know what they should do; they inquire of God; they wait upon him, in his word and ordinances, for direction; and, being informed, do it with all their might, and follow the Lamb wheresoever he goes or directs them: and they look unto him for strength to assist them therein, being conscious of their own weakness; they apply to him, and wait upon him for strength, and do all they do in his name and strength; they look unto him for protection from all their enemies, which are many and mighty, and are stronger than they; and for food, both temporal and spiritual, and for all the necessaries and comforts both of a corporeal and spiritual life; and likewise for the recompence of reward, the reward of the inheritance, which is of grace, and not of debt.
Joseph Kimchi thinks that the allusion is to servants, that look to the hand of their masters that correct and chastise them, and bear it patiently; and look to the hand that smites, till it shall have done, and mercy is shown them.
And thus the saints look to the chastising hand of God, and humble themselves under it, and patiently endure it, till the Lord shall please to remove it from them; and this agrees with what follows:until that he have mercy upon us; God is gracious and merciful; and he has his set time to have mercy on his people: and it becomes them to continue praying to him, and waiting on him, until he is pleased to show it to them; men should pray always, and not faint; they will find mercy in due time, Lu 18:1.
