A.T. Robertson Commentary John 14:5

"Thomas saith unto him, Lord, we know not whither thou goest; how know we the way?" — John 14:5 (ASV)

Whither (που)-- how (πως). It is Thomas, not Peter (13:36f.) who renews the doubt about the destination of Jesus including the path or way thither (την οδον). Thomas is the spokesman for the materialistic conception then and now.
