Exodus 21:2-6 gives the same law of Hebrew slaves serving six years and going free in the seventh — a parallel restatement.

Jeremiah 34:14 explicitly cites this law, rebuking Israel for disobeying the command to release Hebrew slaves after six years.

Exodus 21:3 clarifies the release conditions for a slave who entered married, a specific case related to the general law here.

Jeremiah 34:8 records a historical covenant to free Hebrew slaves, directly applying the law from Deuteronomy.

Jeremiah 34:9 describes the actual freeing of Hebrew slaves, fulfilling the command in Deuteronomy.

Leviticus 25:39-41 provides a different release law (Jubilee) for Hebrew slaves — related but with a longer term, complementing this six-year rule.
