1: δοῦλος
(Strong's #1401 — Noun — doulos — doo'-los )

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 6:17,20 , 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.

2: παιδίσκη
(Strong's #3814 — Noun Feminine — paidiske — pahee-dis'-kay )

"a young girl, maiden," also denoted "a young female slave, bondwoman, or handmaid." For the AV, "bondmaid" or "bondwoman," in Galatians 4:22,23,30,31 , the RV has "handmaid." See DAMSEL , HANDMAID, MAID.
