nor does the Bible treat them as such.
Slavery...barely mentioned and never condemned...it was simply a way of life for many then and beat being killed after defeat/conquest
Murder...wholly condemned...see the tablets.
Polygamy....sort of accepted to some degree though much of the Bible is devoted in matrimony as between one man and one woman.
Murder as opposed to justifiable killing is consistently condemned in the Bible.
Yes you are correct. Polygamy, slavery and murder are not the same.
My point is that they are all in the Bible. It is clear that murder is a sin. It is implied that slavery and polygamy are sins.
Maybe you should dust off your Bible.
The Bible condemned slave traders (1 Tim. 1:9-11) & kidnapping for slavery (Ex. 21:16); advised against returning escaped slaves (Dt 23:15-16); and advised slaves to gain freedom (Moses & Paul...Paul 1 Cor. 7:21-23).
Of course, there's some passages where some have thought God "condoned" slavery or was more neutral toward it...see Deut 15; Ex 21; 1 Pet. 2:18; Eph. 6;5-9: Titus 2:9-10; Col. 3:22-25; 1 Tim. 6:1)...but again, first of all, many of the "slaves" of the era were "bondservants"--meaning they were paying off an economic debt...would be released after a certain # of yrs. (no credit in those days)...secondly in many households, servants were treated as family members; For these slaves, anyway, that was no comparison to the slave-as-property mentality of American & Muslim slavery. (Certainly other slaves acquired by conquering warriors were nowhere near treated "like family").
My point is that in Biblical times, there were "degrees" of slavery, from temporary bond-servants to those treated like "plunder" captured after a victorious battle. From servants treated like family members to those abused. (Note, too that God didn't rush in to rescue the Israelites from bondage in Egypt...they were there over 400 years...how many generations is that? Did that mean God "condoned" it? No. But how would we know about spiritual debt & spiritual slavery unless He allowed real-life slavery. How would we know about spiritual warfare unless He allowed real warfare? "Allowance" and "condoning" are NOT the same attitudes.)
Polygamy....sort of accepted to some degree though much of the Bible is devoted in matrimony as between one man and one woman.
Hey, adultery wasn't even outlined til Exodus 20...so can't hold up Genesis folks as "family standards." Beyond that, I can only think of three characters (David, Gideon, & Caleb) who had concubines who were otherwise "positive" in character most of the way through their lives. {The others are hardly role models of other aspects of their lives, anyway).
If you think it was "tolerated" then I guess you'd have to hold up Absalom & Rueben--both who as adult sons slept with their fathers' concubines--as similar acts of "acceptance" (Absalom, son of David; Rueben, son of Jacob).
