But because he did not have the means to pay, his lord commanded him to be sold, and his wife and children, and all that he had, and payment to be made. Bible

“His lord commanded him to be sold…” Slave owners were under no obligation to keep families together, and it was common for slave families to be separated by being sold one by one to others, although sometimes more compassionate owners tried to keep families together. This was at least as true in Rome as in Israel and the other countries of the East. Furthermore, people sometimes even sold their own children to pay their debt (Nehemiah 5:5).
