“Take the Levites” – that is what the verse said: “The Lord assesses the righteous, but He hates the wicked and the lover of villainy” (Psalms 11:5). “The Lord assesses the righteous” – the Holy One blessed be He does not elevate a person to a position of authority until he first assesses and examines him. When he passes His ordeal, He elevates him to a position of authority. Likewise, you find regarding Abraham our patriarch.
The Holy One blessed be He subjected him to ten ordeals and he passed them. Then He blessed him: “The Lord blessed Abraham with everything” (Genesis 24:1). Likewise, Isaac, He subjected him to the ordeal of Avimelekh, and he passed the ordeal. Then He blessed him, as it is stated: “Isaac sowed in that land and found in that year one hundredfold, and the Lord blessed him” (Genesis 26:12).
Likewise, Jacob our patriarch, He subjected him to an ordeal with all those travails; with Esau, with Rachel, with Dina, with Joseph, and how he left his father’s house: “For with my staff I crossed this Jordan” (Genesis 32:11). And He blessed him: “God appeared to Jacob again, already upon his arrival from Padan Aram, and He blessed him” (Genesis 35:9). Likewise, Joseph with the wife of Potifera; he was incarcerated for twelve years and became king because he passed his ordeals.
That is, “the Lord assesses the righteous.” The tribe of Levi, too, devoted their lives for sanctification of the name of the Holy One blessed be He. When Israel was in Egypt, they rejected the Torah and circumcision, as Ezekiel rebukes them: “So said the Lord God: On the day that I chose Israel, I raised My hand to the descendants of the house of Jacob and made Myself known to them in the land of Egypt” (Ezekiel 20:5).
What is ultimately written thereafter? “They defied Me and did not want to heed Me…and I said to pour My fury upon them” (Ezekiel 20:8). What did the Holy One blessed be He do? He brought darkness upon the Egyptians for three days, during which he killed all the wicked of Israel, as it says: “I will purge the rebels and the transgressors against Me from among you” (Ezekiel 20:38).
Likewise it says: “The fig tree formed its unripe figs” (Song of Songs 2:13), these are the wicked who were among Israel. “And the vines, budding, emitted fragrance” (Song of Songs 2:13), the survivors who repented were accepted. “Arise, my love, my fair one, and go” (Song of Songs 2:13), as the time of the redemption has arrived. But the tribe of Levi, all of them were righteous, and all of them would perform the Torah, as it is stated: “For they observed Your saying, and Your covenant they upheld” (Deuteronomy 33:9); this is circumcision.
Moreover, when Israel crafted the calf, the tribe of Levi did not participate, as it is stated: “Moses stood at the gate of the camp…and all the sons of Levi gathered to him” (Exodus 32:26). When Moses said to them: “Each man, place his sword upon his thigh” (Exodus 32:27), what did they do? They placed it and showed no favor. Likewise, Moses said in his blessing: “Who said of his father and of his mother: I have not seen him” (Deuteronomy 33:9).
When the Holy One blessed be He saw that they were all righteous, he subjected them to an ordeal and they passed the ordeal, as it is stated: “Whom you subjected to an ordeal at Masa” (Deuteronomy 33:8). Immediately, He said: “The Levites shall be Mine” (Numbers 8:14), to realize what is stated: “The Lord assesses the righteous” (Psalms 11:5). But the wicked, it is written in their regard: “But He hates the wicked and the lover of villainy” (Psalms 11:5). David said: “Happy is everyone who fears the Lord, who walks in His ways” (Psalms 128:1).
