'Free' in the Bible

"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.

But when you set them free, don't send them away empty-handed.

Don't view this as a hardship for yourself when you set him free, for he will have served you for six years twice the time of a paid worker. Then the LORD will bless you in all that you do."

For the LORD will vindicate his people and bring comfort to his servants, because he will observe that their power has waned, when neither prisoner nor free person remain.
