Luke 22:35

‘And he said to them, “When I sent you forth without purse, and wallet, and shoes, did you lack anything?” And they said, “Nothing.” '

His first emphasis was to draw attention to how God had provided for them in the past as they went forward in His service. Their sending forth in this way is described in Luke 10:4 (of the seventy, which would include the twelve). So He made them now admit that when they had gone forward without purse, or food pouch or shoes, they had lacked for nothing.
