ST. MATTHEW; 20; 22; But Jesus answered and said; Ye know not what ye ask,Are ye able to drink of the cup that Ishall drink of, and to be baptized with the baptism that I am baptized with? They say unto him,We are able.23; And he answered unto them, Ye shall drink indeed of my cup,and be baptized with the baptism that I am baptized with; [ This baptism Jesus was talking about was the Holy Ghost, because none had recieved it until he ascended. They all had already been baptized with water by John .
