There were two separate sets of laws regarding slavery. Those that you referred to involve fellow Israelites. I am not objecting to that arrangement in this thread. I am only concerned with god's commands to take slaves as permanent possessions from non-Israelite nations.
An Israelite was instructed to take slaves by force. To own them as part of their personal possessions. To pass them on as part of their estate. If the save owner beat the slave to death there was no punishment as long as the slave did not die on the same day. The justification for this cruelty was the according to god "no vengeance shall be taken; for he is his property."
God also instructed Israelite soldiers to kidnap sex slaves. These young virgins had no choice but to be married of to their captors.
During their campaigns god also instructed his army to specifically target women and babies to be hacked to death after the enemy army had been defeated.
The deity who did these things was the god and father of Jesus.
According to your claims about objective morality you are forced to declare all of these actions to be morally perfect. If you would like me to supply biblical references for all of these incidents please ask, it's no problem.
