John Lightfoot on Matthew 10:23

[Ye shall not have gone over the cities of Israel, &c.] "Ye shall not have travelled through the cities of Israel preaching the gospel, before the Son of man is revealed by his resurrection," (Romans 1:4. Lay to this Acts 3:19,20, "Repent ye therefore, and be converted, that your sins may be blotted out, that the times of refreshment may come" (for ye expect refreshment and consolation under the Messias); "and he may send Jesus Christ first preached to you." And verse 26, "To you first God, raising up his Son, sent him to bless you," &c. The epoch of the Messias is dated from the resurrection of Christ.
