Augustine of Hippo
Catena Aurea · Johannesevangelium 16
His disciples said unto him, Lo, now speakest thou plainly, and speakest no proverb. Now are we sure that thou knowest all things, and needest not that any man should ask thee: by this we believe that thou camest forth from God. Jesus answered them, Do ye now believe? Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me. These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
(Tract. ciii. 3) The tribulation of which He speaks was to commence thus, i. e. in every one being scattered to his home, but was not to continue so. For in saying, And leave Me alone, He does not mean this to apply to them in their sufferings after His ascension. They were not to desert Him then, but to abide and have peace in Him. Wherefore He adds, Be of good cheer.
