Eph 6:5. Οἱ δοῦλοι, servants) He here speaks broadly, namely, of slaves, and of freedmen as a species next to slaves, Eph 6:8, at the end.-τοῖς κυρίοις κατὰ σάρκα, to your masters according to the flesh) It was not proper, after making mention of the true Master [the Lord], Eph 6:4, that such persons should also immediately be absolutely called masters; on that account the rather, he adds, according to the flesh.-μετὰ φόβου καὶ τρόμου, with fear and trembling) precisely as if threatenings, so far as believing masters are concerned, were not taken away, Eph 6:9. He has regard to the condition of slaves in ancient times.-ἁπλότητι τῆς καρδίας, in singleness (simplicity) of heart) So the LXX. for the Heb. לֵבָב ישֶׁר, 1Ch 29:17. This is explained in the following verses, who eye-service is chiefly opposed to singleness; comp. Col 3:22. Slavery is subjected [made subordinate] to Christianity, and not to be considered as joined with it [non committenda cum illo].
