Exodus 21:7 NASB: Now if a man sells his daughter as a female slave, she is not to go free as the male slaves do
It is clear slaves were treated as property and they were treated similarly both males and females in most situations
Exodus 21:20-21 NASB: And if someone strikes his male or female slave with a rod and the slave dies at his hand, he shall be punished. If, however, the slave survives a day or two, no vengeance shall be taken; for the slave is his property.
Exodus 21:26-27 NASB: And if someone strikes the eye of his male or female slave and destroys it, he shall let the slave go free on account of the eye. And if he knocks out a tooth of his male or female slave, he shall let the slave go free on account of the tooth.
But what is not clear is the distinction between male and female slaves when it comes to freedom.
What is the reason for not setting free the female slaves?
