dontconvert2islam tries talking human rights, what is a slave in the Bible?

In answer to the video "Muhammad's Jewish Wife"

Slavery wasnt invented by Islam or Christianity, it existed long before. In ancient times almost all nations from the Romans to the Greeks regarded slavery as something natural. Aristotle thought that

"..some men are by nature free, and others slaves, and that for these latter slavery is both expedient and right."

The elites throughout India, Persia, Rome, the Arabian Peninsula, Romania and Greece regarded them as some commodity not worthier than cattle and had the power of life or death over them. The Judeo-christian scriptures hardly improved the status of slaves, as human traficking was allowed even if it involved one's own children. Severly scourging the slave was permissible so long as the beating did not immidiately bring about the slave's death Ex21:20-1. The mosaic law, which Jesus abided by to the letter and instructed his followers to do the same, still allows purchasing them like any other commodity, detaining them and passing them down against their will Lev25:44-46,Deut15:16-17. Slaves can be forcefully seperated from their wives married under slavery, and from their children who are to stay with the master should the slave request and gain his freedom Ex21:2-4. By keeping his family as hostages, the master is almost sure to keep his slave permanently. For hard labor purposes, the only restriction to slave acquisition is that it was forbidden for Jews to enslave one another for hard labor. However, throughout history they could, and did, sell one another to slavery for a different purpose than their non-Jewish slaves, they were employed for works that did not involve physical toil Lev25:40-46. Solomon, during the building of the Temple and his own palace made ample use of non-Jewish slaves during 20 years of hard labor.

Slaves had to lookup to their masters as equals of God Col3:22-24, respect and fear them in servitude as they would serve Jesus Ephes6:5, submit to even harsh masters 1Pet2:18. So inconceivable is it that a slave may one day rise above his cursed status and gain responsibilities that the earth is pictured as quacking at the thought of it Prov30:21. The subjugation of a slave is an essential part of religion

1Tim6:1-4"so that God’s name and our teaching may not be slandered..These are the things you are to teach and insist on. If anyone teaches otherwise and does not agree to the sound instruction of our Lord Jesus Christ and to godly teaching, they are conceited and understand nothing".

As stated earlier, being nothing more than an ISraelite prophet in a long line of prophets, Jesus himself never banned slavery and in fact even endorsed unquestioned submission of slaves to their masters Lk17:7-10. Slave trafficking became an organized business through the Christian nations of Europe and America who captured slaves by thousands from their colonies.
They packed them like sardines in ships according to a precise mathematical calculation to maximize profit and many died on the way. Before leaving, the ships were blessed by priests. Christian priests themselves participated in the trade, especially in Angola, and justified it by saying they were baptizing them. Towards the end of the 18th century, some Arab nations participated in the slave trade too.

The end of slavery in the christian world did not come by the hand of the church. It was a handful of moralists who rose slowly against it. Their cries werent heard in britain until 1807 when it was no longer profitable to the economy and the governement wanted to cut expenses especially in the sugar plantations after they lost their global monopoly.

The prophetic traditions are clear as regards the treatment of slaves. In his famous sermon in 'Arafat, on 9th Dhul-hijjah 9 AH, during his last pilgrimage, the Prophet said,

"...and your slaves, see that you feed them such food as you eat yourselves and dress him with what you yourself dress. And if they commit a mistake which you are not inclined to forgive then sell them, for they are the servants of Allah and are not to be tormented..."

As a side note, the selling refered to here is certainly not in the context of trade. It is the best solution for both parties to seperate with lesser harm. The guardian is here confronted to a situation where the slave comits a grave offense. The prophet's compassionate words refer to the slave's misdeed as a mistake, although from the guardian's perspective it is unforgivable and deserving of a harsh treatment.
This wording of the prophet is in line with the Quranic injuntions of being more lenient towards the weaker members of society in case of an offense 4:25. The conditions for having a slave in Islam, as already shown, is costly. Parting with them could not be done immidiately because the guardian had to recover some of his investment somehow. He would thus be tempted to become harsh towards his slave until he could get back some of his costs and then free him. The prophet thus proposes a pragmatic solution that keeps in view justice, with the guardian recovering some of his investment, and compassion, with the slave avoiding punishment and being transferred to a new household where he could have a fresh start.

From Risalat al-Huqooq

"And the right of your subject through being your slave is that you should know that he is a creature of your Lord and is made of the same flesh and blood. And you only own him, but you are much too inferior to God and you have not created him. And you have not created his hearing and sight, nor do you provide his daily sustenance; rather it is God who gives you sufficiency for that. Then He subjugated him to you, entrusted him to you, and provisionally consigned him with you. So protect him there, and treat him well, just as He (God) has treated you well, and feed him with what you eat yourself, and clothe him with what you clothe yourself. And do not burden him with what he cannot withstand. And if you dislike him, you ought to let him go and replace him, but do not torment God's creature. And there is no power but in God". Slaves are even covered by the law of equal retribution "Samurah ibn Jundub narrated that the Prophet had said: “He who kills his slave shall be killed, he who amputates his slave shall be amputated and he who castrates his slave shall be castrated.”
