Augustine of Hippo — as excerpted in the Catena Aurea on Luke 21:34-36

“(de Con. Ev. l. ii. c. 77.) This is supposed to be that flight which Matthew mentions; which must not be in the winter or on the sabbath day. To the winter belong the cares of this life, which are mournful as the winter, but to the sabbath surfeiting and drunkenness, which drowns and buries the heart in carnal luxury and delight, since on that day the Jews are immersed in worldly pleasure, while they are lost to a spiritual sabbath.”
