J. B. Lightfoot on Colossians 2:22

ἐντάλματα καὶ διδασκαλίας τῶν ἀνθρώπων· τὰ ἐντάλματα κ.τ.λ.] The absence of both preposition and article before διδασκαλίας shows that the two words are closely connected. They are placed here in their proper order; for ἐντάλματα describes the source of authority and διδασκαλίας the medium of communication. The expression is taken ultimately from Isaiah xxix. 13, where the words run in the LXX, μάτην δὲ σέβονταί με, διδάσκοντες ἐντάλματα ἀνθρώπων καὶ διδασκαλίας. The Evangelists (Matt. xv. 9, Mark vii. 7), quoting the passage, substitute in the latter clause διδάσκοντες διδασκαλίας ἐντάλματα ἀνθρώπων. The coincidences in St Paul’s language here with our Lord’s words as related in the Gospels (Matt. xv. 1–20, Mark vii. 1–23) are striking, and suggest that the Apostle had this discourse in his mind. (1) Both alike argue against these vexatious ordinances from the _perishableness_ of meats. (2) Both insist upon the indifference of such things in themselves. In Mark vii. 19 the Evangelist emphasizes the importance of our Lord’s words on this occasion, as practically abolishing the Mosaic distinction of meats by declaring all alike to be clean (καθαρίζων; see the note on ver. 16). (3) Both alike connect such ordinances with the practices condemned in the prophetic denunciation of Isaiah.
