It is not irrelevant to the discussion you were having with Rnmomof7 about the different baptisms in Scripture. IIRC, you stated that all mentions of the word "baptism" meant water baptism. This was another example where Jesus spoke of baptism and it was definitely not water baptism.
Your recollection is flawed. Please reread my post #3727.
And, being assembled together with [them], commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, [saith he], ye have heard of me. For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence. Acts 1:4-5
And as I began to speak, the Holy Ghost fell on them, as on us at the beginning. Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost. Acts 11:15-16
