1Jesus summoned His twelve disciples and gave them authority over unclean spirits, to cast them out, and to heal every kind of disease and every kind of sickness.
Mat_10:1 "twelve" This is the first time this number is stated, possibly corresponding to the twelve tribes of Israel. See Special Topic: The Number Twelve at Mat_14:20.
▣ "disciples" This is literally "learners." The New Testament emphasizes disciples, not just decisions (cf. Mat_28:19; Act_14:21)! The Special Topic below addresses this theological distinction.
▣ "gave them authority over unclean spirits, to cast them out" Jesus empowered these followers with His power. They became His official representatives (i.e., Apostles). The physical miracles were a way of confirming Jesus' new message.
▣
"unclean spirits. . .heal every kind of disease" Notice a distinction is made between demon possession and disease. Demons can cause diseases, but not always.
