'Slave' in the Bible

You are to remember that you were a slave in the land of Egypt, but the LORD your God brought you out from there with great power and a show of force. Therefore, the LORD your God has commanded you to observe the Sabbath day.

"When a fellow Hebrew male or female slave is sold to you and serves you for six years, then in the seventh year you are to set them free.

Don't ever forget that you were a slave in the land of Egypt, yet the LORD your God redeemed you. Therefore, I'm giving you these commands today.

"Should that slave say to you, "I won't leave you,' because he loves you and your household, and it was good for him to be with you,

then take an awl and pierce through his earlobe into the door. Then he will be your slave forever. You are to do the same for your female slaves.

"Don't hand over a slave who escaped from his master when he runs to you.
