Charles Spurgeon Commentary Matthew 10:15

"Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrah in the day of judgment, than for that city." — Matthew 10:15 (ASV)

The accursed cities of the plain may anticipate a fearful doom, but their fate will not be so unbearable as that of those to whom the Gospel comes most freely, and yet they will not receive its messengers, nor even hear their words. With what solemnity do these threats surround both the preaching and the hearing of the kingdom! Our Lord seals His terrible prophecy with a Verily and with that solemn introduction, I say unto you.

Here our ever-blessed King sends forth His royal ambassadors under orders to summon the Jewish nation to acknowledge their sovereign Lord, and He supports them in their mission by a tremendous threat of doom to those who will not receive them or listen to their words.
