The words that are translated here as "male and female servants" are normally translated as "boys" and "girls." They may indicate that the servants were young or that they were dear to their master.
Possible meanings are 1) this is an exaggeration for the master dealing out harsh punishment toward the slave, or 2) this describes the manner in which the servant will be executed and buried as punishment. (See: [[rc://en/ta/man/translate/figs-hyperbole]])
