Jesus sent out his Disciples in pairs
Mark Chapter 6 - Jesus Sends Out the Twelve Apostles
7 And he called the twelve and began to send them out two by two, and gave them authority over the unclean spirits. 8 He charged them to take nothing for their journey except a staff no bread, no bag, no money in their belts 9 but to wear sandals and not put on two tunics. 10 And he said to them, "Whenever you enter a house, stay there until you depart from there. 11 And if any place will not receive you and they will not listen to you, when you leave, shake off the dust that is on your feet as a testimony against them." 12 So they went out and proclaimed that people should repent. 13 And they cast out many demons and anointed with oil many who were sick and healed them.
Luke Chapter 10
The Return of the Seventy-Two
17 The seventy-two returned with joy, saying, "Lord, even the demons are subject to us in your name!" 18 And he said to them, "I saw Satan fall like lightning from heaven. 19 Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. 20 Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven."
