J. B. Lightfoot on Colossians 2:20

ἀπὸ τῶν στοιχέιων τοῦ κόσμου, τί ὡς ζῶντες ἐν κόσμῳ ἀπὸ τῶν στοιχείων κ.τ.λ.] i.e. ‘from the rudimentary, disciplinary, ordinances, whose sphere is the mundane and sensuous’: see the note on ver. 8. For the pregnant expression ἀποθανεῖν ἀπὸ comp. Gal. v. 4 κατηργήθητε ἀπὸ Χριστοῦ (so too Rom. vii. 2, 6), 2 Cor. xi. 3 φθαρῇ ... ἀπὸ τῆς ἁπλότητος, and see A. Buttmann p. 277 note.
