besides their male slaves and their female slaves, of whom there were 7,337;
and they had 200 singing men and singing women. Bible see other translations

“their male slaves and their female slaves.” There were 42,360 Jews who returned from Babylon, and 7,337 slaves, so there was a large ratio of slaves to free Jews, roughly one to six. That so many slaves opted to return to Judea with their owners, when it is almost certain they would not have had to, shows that in general, the Jews had very good relationships with their slaves.
