“And as ye go, preach, saying, The kingdom of heaven is at hand.”
Matthew 10:7 — Greek Interlinear
Church Fathers on Matthew 10:7
Because the manifestation of the Spirit, as the Apostle speaks, is given for the profit of the Church, after bestowing His power on the Apostles, He sends them that they may exercise this power for the good of others; 'These twelve Jesus sent forth.'
Observe the propriety of the time in which they are sent. After they had seen the dead raised, the sea rebuked, and other like wonders, and had both in word and deed sufficient proof of His excellent power, then He sends them.
This passage does not contradict the command which He gave afterwards, 'Go and teach all nations;' for this was before His resurrection, that was after. And it behoved the coming of Christ to be preached to the Jews first, that they might not have any just plea, or say that they were rejected of the Lord, who sent the Apostles to the Gentiles and Samaritans.
