These [are] those that were numbered
 Or, as the Targum of Jonathan, these are the sums of the numbers; namely, those before given of the several respective tribes: 
 which Moses and Aaron numbered, and the princes of Israel, [being]
 twelve men;
 for though the tribe of Levi was not numbered, yet Joseph having a double portion, his two sons are reckoned as distinct tribes; so that one out of each tribe made up the number twelve: 
 each one for the house of his fathers;
 for the tribe he belonged to, with which it might reasonably be supposed he was best acquainted, and could more readily take the number of them.
