Rashi on Numbers 23:21/רש"י על במדבר כ״ג:כ״א

1לא הביט און ביעקב וגו׳ HE HATH NOT BEHELD INIQUITY IN JACOB, etc. — Understand this as the Targum has it (“I have seen that there are no worshippers of idols in the house of Jacob”). Another explanation: According to its plain sense it can receive a beautiful exposition:

2לא הביט HE DOTH NOT SEE — i. e., the Holy One, blessed be He, doth not see און THE INIQUITY which is IN JACOB: when they transgress His Words He does not deal so strictly with them as to pay regard to their iniquitous doings and their transgression by which they infringe His law (cf. Midrash Tanchuma, Balak 14).

3עמל denotes transgression, as in (Psalms 7:15): “He conceiveth transgression (עמל)"; (Psalms 10:14) “For thou beholdest transgression (עמל) and vexation” — and it denotes this because transgression is a vexation (עמל) before the Omnipresent.

4ה' אלקיו עמו THE LORD HIS GOD IS WITH HIM — Even when they provoke Him to anger and act rebelliously before Him He does not depart from their midst,

5ותרועת מלך בו BUT THE תרועה OF A KING IS STILL WITH THEM — תרועה is an expression for love and fellowship, as (II Samuel 15:37) “the רעה of David’ — the friend of David; (Judges 15:6) “And he gave her to his friend (מרעהו)." (The translation is therefore: and the fellowship of their king is still with them). In this sense, too, does Onkelos translate it: and the Shechina of their King is among them.
