Комментарий к Дварим 33:11

מחץ מתנים קמיו means, smite those who rise up against him with a smiting of the loins, similar to the idea that is expressed, (Psalms 69:24) “Make their loins continually to totter”. It was about those who contested the High priesthood that he spake thus. — Another explanation: He foresaw that Hasmon and his sons would in future war with the Greeks, and he therefore prayed for them, because they were few in number, viz., the twelve sons of Hasmon and Eleazar against several myriads of the enemy. On this account he prayed ברך ה׳ חילו ופעל ידיו תרצה BLESS, O LORD, HIS ARMY AND ACCEPT FAVOURABLY THE WORK OF HIS HANDS (cf. Genesis Rabbah 99:2; Midrash Tanchuma, Vayechi 14).

BLESS, ETERNAL, ‘CHEILO’ — that they be a great chayil (army). And the meaning thereof is that they should increase and not decrease when they enter the Holiness, similar in meaning to the verse, Cut ye not off the tribe of the families of the Kohathites.¹⁸⁶Numbers 4:18. It is similarly stated in the admonitions concerning [the Levites], and that they may not die.¹⁸⁷Ibid., Verse 19. And Onkelos rendered cheilo — “his possessions,” from the expression and all their flocks, and all ‘cheilam’ (their possessions).¹⁸⁸Ibid., 31:9. He means what our Rabbis have said concerning the incense — that it bestows a blessing [upon the priest that performs that service].¹⁸⁹Yoma 26a. The phrase [before us] is connected with the expression in [the preceding verse], they shall put incense before Thee,¹⁸⁵Verse 10. because, as a result of it, his possessions will be blessed, as we have been taught:¹⁸⁹Yoma 26a. “Fresh priests come and draw lots for the incense.”¹⁹⁰Four lots were drawn to determine the priests who would be privileged to minister in the Service of the Daily Whole-offering. Three of these lots were open to any priest whose family served that day. But prior to the lot for the burning of the incense the officer announced, “Fresh priests etc.,” i.e., those who had never yet performed the incense service were to come forward. The reason for this arrangement was to give as many priests as possible the opportunity to participate in the burning of the incense, because those who did so became wealthy. And in the Sifre it is stated:¹⁹¹Sifre, Brachah 352. “Bless, Eternal, ‘cheilo’ — his possessions. From here the Rabbis have deduced: Most priests are wealthy. In the name of Abba the Preacher the Rabbis have said: I have been young, and now am old; yet have I not seen the righteous forsaken¹⁹²Psalms 37:25. — this refers to the seed of Aaron.”

ברך ה' חילו, "please G’d bless their worldly activities," so that by making an easy livelihood they can devote themselves to instructing the people in your Torah.
