Leviticus 25:42

The same Hebrew word means both servants and slaves. The Israelites were God's servants, so they could not be slaves to other people. They could only serve temporarily to pay off a debt.

Just as seven days made a week ending in a Sabbath day, every seven years ended with a Sabbath year. After seven Sabbath years, or 49 years, came a special year called the Year of Jubilee. Like so many holy days, these times were meant for reflecting on Israel's shared identity and their relationship with God.

Every Israelite, both free and servant, had a place in God’s kingdom. So, those bound in servitude were set free during the Year of Jubilee (Leviticus 25:39–43). To reduce poverty and protect families, land sales were limited to fifty years. After that, the land returned to the original owner's family or clan.

The land belonged to God, and the Israelites were only "residents" (25:23). But it is unlikely that they actually used these laws. The best land ended up belonging to wealthy landowners (Isaiah 5:8–10; compare Amos 5:11).
