Bondman, Bondmaid - Vine's Expository Dictionary of New Testament Words
Bondman, Bondmaid
[ 1,,G1401, doulos ]from deo, to bind," "a slave," originally the lowest term in the scale of servitude, came also to mean "one who gives himself up to the will of another," e.g., 1 Corinthians 7:23; Romans 6:17, Romans 6:20, and became the most common and general word for "servant," as in Matthew 8:9, without any idea of bondage. In calling himself, however, a "bondslave of Jesus Christ," e.g., Romans 1:1, the Apostle Paul intimates
(1) that he had been formerly a "bondslave" of Satan, and
(2) that, having been bought by Christ, he was now a willing slave, bound to his new Master. See SERVANT.
The feminine, doule, signifies "a handmaid," Luke 1:38, Luke 1:48; Acts 2:18.
[ 2,,G3814, paidiske ]
"a young girl, maiden," also denoted "a young female slave, bondwoman, or handmaid." For the AV, "bondmaid" or "bondwoman," in Galatians 4:22-Galatians 4:23, Galatians 4:30-Galatians 4:31, the RV has "handmaid." See DAMSEL, HANDMAID, MAID.
