Numbers 31:15
And Moses said unto them, Have ye saved all the women alive?
And Moses said unto them, Have ye saved all the women alive? Which either had been reported to him, or he concluded, by seeing so many with them; and this question is put, not for information, but by way of reproof, and as chiding them for what they had done; for they might have received orders from him to put them to death, when he sent them out; and if so, there was the more reason to be angry with them; or he might conclude they would have done this of themselves, knowing what instruments of mischief these women had been to Israel.
