But they that wait upon the Lord – The word rendered ‘wait upon’ here (from קוה qâvâh), denotes properly to wait, in the sense of expecting. The phrase, ‘to wait on Yahweh,’ means to wait for his help; that is, to trust in him, to put our hope or confidence in him. …It means that the people of God who trust in him shall become strong in faith; able to contend with their spiritual foes, to gain the victory over their sins, and to discharge aright the duties, and to meet aright the trials of life. God gives them strength, if they seek him in the way of his appointment – a promise which has been verified in the experience of his people in every age.
