Origen, on Exod 17:11

“And when Moses lifted up his hands, Israel overcame: but if he let them down a little, Amalec overcame.”

“For in this way, when the eyes are lifted up through thought and contemplation and the hands are lifted up in deeds which lift up and exalt the soul, as Moses lifted up his hands, one may consequently say, "The lifting up of my hands is as the evening sacrifice." In this way the Amalekites and all the unseen enemies will be worsted, and the Israelite reasonings in us will prevail.”
