ייִדישער מחשבֿה אויף ישעיהו 8:21

As written "And I will wait for the L-ord, that hides His face from the house of Jacob, and I will hope unto Him" (Yeshaya 8:17), and he should not be like the one the verse speaks of: "and it shall come to pass that, when they shall be hungry, they shall fret themselves, and turning their faces on high, curse by their king and by their G-d" (Yeshaya 8:21).

But one who does not trust in the Al-mighty boasts on the good (saying "it is due to my might and ingenuity, etc" - PL) as written "For the wicked boasts of his heart's desire" (Tehilim 10:3), and he becomes angry on the bad as written "And the one who passes therein shall suffer hardships and hunger, and it shall come to pass,] that when he shall be hungry, he shall be enraged, and curse his king and his [idolatrous] god, and he will turn to Heaven" (Yeshaya 8:21).
