John Chrysostom (attributed)

He says not ‘Angels descended from heaven,’ that it may be known that they were ever on the earth to minister to Him, but had now by the Lord’s command departed from Him, to give opportunity for the Devil to approach, who perhaps when he saw Him surrounded by Angels would not have come near Him. But in what matters they ministered to Him, we cannot know, whether in the healing diseases, or purifying souls, or casting out dæmons; for all these things He does by the ministration of Angels, so that what they do, Himself appears to do. However it is manifest, that they did not now minister to Him because His weakness needed it, but for the honour of His power; for it is not said that they ‘succoured Him,’ but that they ministered to Him.
