עבד עברי

When you acquire a Hebrew slave, he shall serve six years; in the seventh year he shall go free, without payment.

(2) If thou shalt have bought a son of Israel, on account of his theft, six years he shall serve, and at the incoming of the seventh he shall go out free without price.

A Hebrew slave is acquired through money or through a document, and acquires himself through years [of service], through the Jubilee Year, or through prorated monetary [payment]. A Hebrew maidservant has an advantage over him, in that she acquires herself through [physical] signs [of puberty]. [A slave] who [has his ear] pierced is acquired through [the] piercing, and acquires himself through the Jubilee Year or with the death of the master.
