'Slaves' in the Bible

And all of you shall have for food whatever the [untilled] land produces during its Sabbath year; yourself, and your male and female slaves, your hired servant, and the foreigners who reside among you,

I am the Lord your God, who brought you out of the land of Egypt so that you would not be their slaves; and I broke the bars of your yoke and made you walk upright [with heads held high as free men].
