Colossians 2:22

Which all are to perish with the using. — It has been doubted whether these words (which are literally, all which things go to corruption, or destruction, in the using) are the continuation of the ascetic ordinance, or the comment of the Apostle. But the last word — which signifies, not only “using,” but “using up” — seems to decide for the latter alternative. The things are things which go to destruction and are used up. What permanent effect can they leave behind? See 1 Corinthians 8:8 (whether the words of St. Paul, or the words of the Corinthians, accepted as true by him), “Meat commendeth us not to God: for neither, if we eat, are we the better; neither, if we eat not, are we the worse.” It is but an echo of our Lord’s own teaching as to that which goeth into the mouth (Matthew 15:16; Mark 13:18).

After the commandments... — See Colossians 2:8, and Note there. There seems to be an allusion to Isaiah 29:13, quoted by our Lord (Matthew 15:7; Mark 7:6) in relation to these ceremonial observances.
