"οἰκέτης," Blue Letter Bible, accessed on November 27, 2023
οἰκέτης, οἰκέτου, ὁ (οἰκέω), from (Aeschylus and) Herodotus down, Latindomesticus, i. e. one who lives in the same house with another, spoken of all who are under the authority of one and the same householder, Sir. 4:30 Sir. 6:11, especially a servant, domestic; so in Luke 16:13; Acts 10:7; Romans 14:4; 1 Peter 2:18; the Sept. for עֶבֶד. See more fully on the word, Meyer on Romans, the passage cited (where he remarks that οἰκέτης is a more restricted term than δοῦλος, designating a house-servant, one holding closer relations to the family than other slaves; cf. διάκονος at the end, Schmidt, chapter 162.)
