Whenever our FATHER sends HIS Children to go tell the world about HIM and/or to bring deliverance to others, HE sends at least two to do HIS mission. We can see this in the Old Testament when HE sent Moses and Aaron or in the New Testament when the Lord YESHUA sent HIS disciples two by two.
Exodus 4:27-29 And the Lord said to Aaron, “Go into the wilderness to meet Moses.” So he went and met him on the mountain of God, and kissed him. So Moses told Aaron all the words of the Lord who had sent him, and all the signs which He had commanded him. [Then Moses and Aaron went and gathered together all the elders of the children of Israel. https://bible.com/bible/114/exo.4.27-29.NKJV
Mark 6:7-11 And He called the twelve to Himself, and began to send them out two by two, and gave them power over unclean spirits. He commanded them to take nothing for the journey except a staff—no bag, no bread, no copper in their money belts— but to wear sandals, and not to put on two tunics. Also He said to them, “In whatever place you enter a house, stay there till you depart from that place. And whoever will not receive you nor hear you, when you depart from there, shake off the dust under your feet as a testimony against them. Assuredly, I say to you, it will be more tolerable for Sodom and Gomorrah in the day of judgment than for that city!”https://bible.com/bible/114/mrk.6.7-11.NKJV
