Colossians 3:23

23. ὅ ἐὰν ποιῆτε. This and the two following verses are an explanation and expansion of φοβούμενοι τὸν κύριον.

ἐκ ψυχῆς. || Ephesians 6:6. Referring not to singleness of purpose (Colossians 3:22), but to ready impulse in contrast to external constraint (cf. Delitzsch Psychol. p. 241 Eng. Trans.), “Worke ye of will” (Wyclif).

ἐργάζεσθε. In connexion with ποιεῖν, also in John 6:28; 3 John 1:5. Of the two ποιεῖν appears to be the more general word, ἐργάζεσθαι to indicate result (“do your work”), not merely toil and fatigue as such (κοπιάω, Colossians 1:29).

ὡς τῷ κυρίῳ καὶ οὐκ�. || Ephesians 6:7. The οὐκ sharply contrasts men with the Lord. They are of course to be serving their earthly masters, but these as such are as nothing compared with Him whom they serve when serving them.
