Adam Clarke on Colossians 2:21

Touch not; taste not; handle not - These are forms of expression very frequent among the Jews. In Maccoth, fol. xxi. 1: "If they say to a Nazarite, Don't drink, don't drink; and he, notwithstanding, drinks; he is guilty. If they say, Don't shave, don't shave; and he shaves, notwithstanding; he is guilty. If they say, Don't put on these clothes, don't put on these clothes; and he, notwithstanding, puts on heterogeneous garments; he is guilty." See more in Schoettgen.
