Numbers 25:5

Each of you must execute his men. Each of the Israelite judges executed two men, and there were eighty eight thousand Israelite judges, as stated in Sanhedrin.

And Mosheh said to the judges of Israel, Slay every one a man of his tribe of those who have joined themselves to the idol of Peor.

[AND MOSES SAID UNTO THE JUDGES OF ISRAEL]: ‘SLAY YE EVERY ONE HIS MEN [THAT HAVE JOINED THEMSELVES UNTO BAAL-PEOR].’ “Each one of the judges of Israel killed two [men, as the word anashav — his ‘men,’ in the plural, indicates], and the judges of Israel were seventy-eight thousand, as is stated in Tractate Sanhedrin.” This is Rashi’s language. But I cannot understand this, that [we should say that] those who joined themselves [to Baal-peor] who were judged [liable to death] were more than a hundred and fifty thousand — a quarter [of the total population] of Israel! Heaven forbid! [Moreover], cases punishable by death [cannot be decided] by [only] one judge, but [require] a court of twenty-three judges. And [even if we were to say that two people were killed by each court of twenty-three judges], they would still be very many people! And the difference between the [two] censuses is not so great, although all those who joined themselves to Baal-peor died, as it is written, for all the men that followed Baal-peor, the Eternal thy G-d hath destroyed them from the midst of thee.
But the meaning of every one his men is that the judges should kill all those who joined themselves [to Baal-peor], that is to say, each court should judge [the men of] its own tribe and its [groups of] thousands, as it is written, So I took the heads of your tribes, wise men, and full of knowledge, and made them heads over you, captains of thousands, and captains of hundreds … and officers, ‘tribe by tribe’., 1:15. The phrase tribe by tribe indicates that each tribe had its own judges who dealt with offenses committed by men of this tribe. And afterwards I found in the Gemara Yerushalmi [the following statement] in the Chapter Cheilek:, see above, Note 228. “And how many were the judges of Israel? Seventy-eight thousand and six hundred. Moses said to them: ‘Each one of you should kill two.’ Thus you find that those killed were one hundred and fifty-seven thousand and two hundred.” If so, we must say that according to their opinion [that of these Rabbis] the Israelites increased very remarkably between the [time of the first] census and the [second] census [in order to make up the loss of the many people killed because of this sin of Baal-peor]!
The correct interpretation of the meaning of this section [of the Torah] appears to me to be that at first it says, And Israel joined himself unto …
