In Matthew 15:14, wherein Jesus charges the Pharisees with leading the
"blind...into the ditch," he seems to be invoking the curse of Deuteronomy 27:18 on his opponents (cf. Lev 19:14). “Cursed be anyone who misleads a blind man on the road.' And all the people shall say, ‘Amen.’”
Speaking, as he did, as the master Torah-expositor, to those who prided themselves as being teachers of the law, it seems certain that the connotations would have been unavoidably obvious to all involved.
