Ecclesiastes 2:7 mentions slaves 'born in my house' — the same category as the children here who become the master’s property.

Genesis 16:2 has Sarai give her slave Hagar to Abram to bear children — a direct parallel to a master giving a slave wife here, with children belonging to the giver.

Genesis 14:14 mentions Abram’s servants 'born in his house' — same status as the slave’s children here who belong to the master.

Genesis 17:13 requires circumcision for slaves born in the house, showing they belong to the master’s household — parallel to the children’s status here.

Genesis 17:27 records Abraham circumcising slaves born in his house, mirroring the legal ownership of such children in this law.
