Mark 8:31-33

And He began to teach them that the Son of Man must [of necessity] suffer many things and be rejected [as the Messiah] by the elders and the chief priests and the scribes, and must be put to death, and after three days rise [from death to life]. [Matt 16:21-28; Luke 9:22-27] He was stating the matter plainly [not holding anything back]. Then Peter took Him aside and began to reprimand Him. But turning around [with His back to Peter] and seeing His disciples, He rebuked Peter, saying, “Get behind Me, Satan; for your mind is not set on God’s will or His values and purposes, but on what pleases man.”
