Ephesians 6:5-6

6:5 Slaves, ¹  obey your human masters ²  with fear and trembling, in the sincerity of your heart as to Christ, 6:6 not like those who do their work only when someone is watching ³  – as people-pleasers – but as slaves of Christ doing the will of God from the heart. ⁴ 

Colossians 3:22

3:22 Slaves, ⁵  obey your earthly ⁶  masters in every respect, not only when they are watching – like those who are strictly people-pleasers – but with a sincere heart, fearing the Lord.

Titus 2:9

2:9 Slaves ⁷  are to be subject to their own masters in everything, ⁸  to do what is wanted and not talk back,

[6:5]  ¹ tn Traditionally, “Servants” (KJV). Though δοῦλος (doulos) is often translated “servant,” the word does not bear the connotation of a free individual serving another. BDAG notes that “‘servant’ for ‘slave’ is largely confined to Biblical transl. and early American times…in normal usage at the present time the two words are carefully distinguished” (BDAG 260 s.v.). The most accurate translation is “bondservant” (sometimes found in the ASV for δοῦλος), in that it often indicates one who sells himself into slavery to another. But as this is archaic, few today understand its force.

[6:5]  ² tn Grk “the masters according to the flesh.” In the translation above, the article τοῖς (tois) governing κυρίοις (kuriois) is rendered in English as a possessive pronoun (i.e., “your”) and the prepositional phrase κατὰ σάρκα (kata sarka) is taken as modifying κυρίοις (indicating that the author is referring to human masters) and not modifying the imperative ὑπακούετε (Jupakouete, which would indicate that obedience was according to a human standard or limitation).

[6:6]  ³ tn Grk “not according to eye-service.”

[6:6]  ⁴ tn Grk “from the soul.”

[3:22]  ⁵ tn On this word here and in 4:1, see the note on “fellow slave” in 1:7.

[3:22]  ⁶ tn The prepositional phrase κατὰ σάρκα (kata sarka) does not necessarily qualify the masters as earthly or human (as opposed to the Master in heaven, the Lord), but could also refer to the sphere in which “the service-relation holds true.” See BDAG 577 s.v. κύριος 1.b.

[2:9]  ⁷ tn See the note on the word “slave” in 1:1.

[2:9]  ⁸ tn Or “to be subject to their own masters, to do what is wanted in everything.”
