John Gill Commentary John 2:5

"His mother saith unto the servants, Whatsoever he saith unto you, do it." — John 2:5 (ASV)

His mother said to the servants
She took the reproof in good part, and by the words he said, and the manner in which he spoke them, or by the looks he gave, and the gestures he might use, she hoped, and even believed, that the thing she moved for would be done; and therefore went immediately to the servants, and gave them the following instructions:

whatsoever he says to you, do [it] ;
punctually observe and obey his orders in every circumstance.
