You continue to ignore actual slavery, which is not voluntary servitude
At the outset, “awful” meant precisely what it sounds like : “full of awe.” Individuals employed it in the 13th century to depict something ““worthy of reverence.” It derives from Old English aghe, an earlier form of “awe” signifying “fright, terror,” in addition the suffix -ful.
Although something “awful” could frighten you, the prevalent meaning these days, “very bad,” was started in 1809.
“Defecate” derives from Latin defaecatus, the past participle of dafaecare, which means “cleanse from dregs; purify.” The Latin verb is a version of the phrase “de faece,” meaning to say “from dregs.”
“Dregs” denotes any fluid remaining in a container along with other sediment — for example left-over java with coffee grounds. At first,” defecate” meant to get rid of the undrinkable bits from a liquid.
There is certainly a definite association, however the excretory sense was initially seen in 1830.
Traditionally, “inmate” was often associated with “roommate.” It is actually a compound expression of “in” (inside) and “mate” (companion), initially showing up in English in the 1580s.
The meaning of an individual kept in an institution came into being in 1834.
Exactly why am I showing all this to you? To make obvious that vocabulary is not fixed but continuously changing. It could actually morph so substantially that definitions may completely transform.
In this case, you're giving the biblical term “slave” a modern, anachronistic meaning instead of recognizing the expression the way it had been employed in the framework of ancient culture.
“Guterbock refers to ‘slaves in the strict sense,’ apparently referring to chattel slaves such as those of classical antiquity. This characterization may have been valid for house slaves whose master could treat them as he wished when they were at fault, but
it is less suitable when they were capable of owning property and could pay betrothal money or fines. The meaning ‘servant’ seems more appropriate, or perhaps the designation ‘semi-free’. It comprises every person who is subject to orders or dependent on another but nonetheless has a certain independence within his own sphere of active.” [A History of Ancient Near Eastern Law:1632] (Emphasis mine.)
“However, the idea of a slave as exclusively the object of rights and as a person outside regular society was apparently alien to the laws of the ANE.” [Anchor Bible Dictionary s.v. "Slavery, Ancient Near East"]
