Ok actually yea that is what it says. Couldn't wait until tomorrow.
Look at Exodus 21:2-6. In this scenario, it specifies that if the wife was not a Hebrew, and the slave man had children with her, her and the children remained with the master. They were never freed, by seniority, by jubilee year, nothing; and they were passed on as inheritance. UNLESS the master chose to free them, which was always his right.
