On this journey, Jesus deliberately makes his apostles dependent on the hospitality of the children of Israel by instructing them not to take provisions. The apostles might expect they are launching a victory tour, but they will learn first-hand how the children of Israel will reject the Messiah.
Matthew presents this initial sending of the Twelve as a first step toward their ultimate global mission. Even though they are to stay in Jewish territory on this journey, ultimately, Jesus is going to send them to the world.
Scripture records the deaths of only 2 apostles: James (Acts 12:1-2) and Judas Iscariot (Matthew 27:5). Most of what we know about the deaths of the other apostles comes from early christian writers and church tradition. Most scholars think the Apostle John is the only apostle who died of natural causes. The exact dates are unknown, most are estimates.
