Thoughts from Matthew 10…
The opposition against Jesus was growing. In the previous section, the Pharisees began to accuse Jesus of healing by the power of the devil (see here). He realized that His time was growing short, and so He was even more urgent in sending His message to all of the Jews. Instead of going alone, He now sent out six teams of disciples to also preach His message of the kingdom. In this way, He was able to successfully cover the entire region of Galilee in a short time.
He chose twelve of His disciples and commissioned them as “apostles” (literally, “one who was sent”).a He gave them His own authority to cast out demons and to heal the sick, and then sent them out two by two.
“The Twelve were disciples before they became apostles. That is, they were learners in the school of Christ before they were commissioned as apostles and sent forth as couriers of the King, to proclaim that the long-looked-for kingdom of the heavens had drawn nigh.” – H.A. Ironside2
“Power is the ability to accomplish a task, and authority is the right to do it, and Jesus gave both to His apostles.” – Warren Wiersbe6
