difference between provide and supply

• To supply something is to make something available as per a request. Supplies are things that you need, such as office supplies, which can be found in office supply stores. It's difficult to make a clear distinction here. 
  
  To provide something is similar to supplying it, such that it is also a response to a need. You can provide the necessary medical attention to an injured person. Provide is different than supply in that you do not necessarily supply your own expertise as you can provide it. You can provide help, but you cannot supply it. Supplying is for things, provide is for anything.

• PROVIDE is use in general conversation whereas SUPPLY is sort of technical and professional word. 
  For example, it is the responsibility of government to provide its every citizen with basic needs. 
  SUPPLY: During war, Pakistani soldier cut Indian army supply line.

• provide: take measures in preparation for; "provide for the proper care of the passengers on the cruise ship"
