Adam Clarke on Matthew 27:41

Chief priests - scribes and elders - To these, several ancient MSS. and versions add, και Φαρισαιων, and Pharisees. But though the authority for this reading is respectable, yet it does not appear that the Pharisees joined in with the others in the condemnation of our Lord. Probably his discourses and parables, related in some of the preceding chapters, which were spoken directly to them, had so far convinced them that they would at least have no hand in putting him to death. All the infamy of this seems to fall upon the Priests, scribes, and elders.
