Zechariah 14:19

This shall be the punishment - of all nations that come not up - God will have his public worship established everywhere, and those who do not worship him shall lie under his curse.

This shall be the sin of Egypt and the sin of all nations that come not up to keep the feast of tabernacles - For before the coming of the Saviour, good perhaps had been in part the excuse of the pagan, that they had been called by none. For no one had preached unto them. Wherefore the Saviour also, pointing out this in the Gospel parables, said, 'the laborers' Matthew 20:7, called 'at the eleventh hour, said, No man hath hired us.' But when Christ cast His light upon us, 'bound the strong man' Matthew 12:29, removed from his perverseness those subject to him, justified by faith those who came to Him, laid down His life for the life of all, they will find no sufficient excuse who admit not so reverend a grace. It will be true of the pagan too, if Christ said of them, 'If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin' John 15:22."

The prophet says "sin," not punishment , for sin includes "the punishment," which is its due, and which it entails: it does not express the punishment, apart from the sin. It was "the sin" which comprised and involved all other sin, the refusal to worship God as He had revealed Himself, and to turn to Him. It was to say, "We will not have" Him "to reign over us" Luke 19:14.
