Charles Ellicott Commentary Isaiah 65:13

"Therefore thus saith the Lord Jehovah, Behold, my servants shall eat, but ye shall be hungry; behold, my servants shall drink, but ye shall be thirsty; behold, my servants shall rejoice, but ye shall be put to shame;" — Isaiah 65:13 (ASV)

My servants shall eat ... — The form of the punishment is apparently determined by that of the sin. That had been the orgy of an idol’s feast; the penalty would be hunger and thirst, while joy and gladness would be the portion of those who had abstained from it. The words present a striking parallelism to Luke 6:20-26.
