Rashi on Numbers 31:32/רש"י על במדבר ל״א:ל״ב

1ויהי המלקוח יתר הבז AND THE PREY, OVER AND ABOVE THE BOOTY … WAS [SIX HUNDRED THOUSAND etc.] — Because they had not been commanded (v. 28) to levy a tribute from the movables but only from the מלקוח (the men and cattle; cf. Rashi on v. 11) it (Scripture) writes this expression: ויהי המלקוח, that which came under the law of being divided (v. 27) and which also came under the law of tribute — which was over and above (יתר) the booty of the movables, אשר בזזו עם הצבא איש לו WHICH THE MEN OF THE HOST HAD PLUNDERED, EACH FOR HIMSELF, and which did not come under the law of being divided, — the number of sheep was etc. (i.e. צאן at the beginning of the second half of the verse means: the number of sheep).
