In whom are hid all the treasures of wisdom and knowledge.
Greek order, 'In whom (not as Alford, "in which" mystery: Christ is Himself the "mystery," Colossians 2:2; 1 Timothy 3:16) are all the treasures of wisdom and knowledge hidden.' The "all" answers to "all" in Colossians 2:2; as "treasures" answers to "riches:" it is from the treasures that the riches are derived. "Are" is the predicate: all the treasures ARE in Him; hidden is predicated of the manner in which they are in Him. Like a mine of unknown wealth, the treasures of wisdom are all in Him, in a hidden manner (to which answers "mystery"): not in order to remain so: they only need to be explored to attain 'unto the riches' in them (Colossians 2:2): until you press after the full knowledge (note, Colossians 2:2) of them, they remain 'hidden.' They do not immediately thrust themselves before carnal men's eyes, but so lie hidden as to be seen by those alone to whom God gives spiritual eyes. Compare Matthew 13:44, "treasure hid." This sense sets aside Alford's objection, that 'the treasures are not hidden, but revealed.' The emphatic reserving of х apokrufoi (G614)] "hidden" to the end of the sentence, shows it is a second predicate; not an epithet, 'the secret treasures of knowledge.' 'Hidden' answers to "mystery" (Colossians 2:2), designed by God, if we use our privileges, not to remain hidden, but to be revealed (cf. 1 Corinthians 2:7-8). Still, as the mine is unfathomable, there will, through eternity, be always fresh treasures in Him to be drawn forth inexhaustibly from their hidden state.
Wisdom - general; concerning experimental and practical truth: whence comes "understanding" (Colossians 2:2).
Knowledge - theoretical and intellectual, in regard to doctrinal truth: whence comes 'the full knowledge' (Col Knowledge - theoretical and intellectual, in regard to doctrinal truth: whence comes 'the full knowledge' (Colossians 2:2).
