ציטירנדיקער פּירוש אויף ישעיהו 22:4

ממני ═ מני Of me. (Comp. 22:4).

ולא שעו And they look not. Lit. They do not resign themselves to the mercy of God.²שעה means literally to turn away (See I. E. on 17:7, and note 11); it is, therefore, usually followed by מן from; but by way of ellipsis, sometimes by אל, so that שעה מן ⋯ אל ═ שעה אל. Comp. שעו מני turn away from me (22:4); to consider שענו ═ שעו is incorrect.³שעו is derived from שעה to turn; שענו from שען to lean.

ואל ישעו בדברי שקר, “let them (the Israelites) not pin their hopes on falsehoods.” According to Ibn Ezra, the meaning of ישעו is derived from the root שען, the letter נ being missing here. The meaning is: “to lean on something for support.” Examples quoted are: השע ממני Psalms 39,14: “look away from me; (do not count on me for support)” also Isaiah 22,4 השע ממני. “leave me alone!” Let them not slacken their labor because of the lies that Moshe and aaron have told them.
