A.T. Robertson Commentary Matthew 10:7

"And as ye go, preach, saying, The kingdom of heaven is at hand." — Matthew 10:7 (ASV)

As ye go, preach (πορευομενο κηρυσσετε). Present participle and present imperative. They were itinerant preachers on a "preaching tour," heralds (κηρυκες) proclaiming good news. The summary message is the same as that of the Baptist (3:2) that first startled the country, "the kingdom of heaven has drawn nigh." He echoed it up and down the Jordan Valley. They are to shake Galilee with it as Jesus had done (4:17). That same amazing message is needed today. But "the apprentice apostles" (Bruce) could tell not a little about the King of the Kingdom who was with them.
