Halakhah su Geremia 17:78

Whoever has no need to take charity, and deceives people and takes, will not die before actually needing charity. Anyone who needs to take [charity], and cannot survive unless he takes [charity], for example, one who is old, sick or suffering, but whose pride doesn't allow him to take [charity], sheds [his own] blood and is liable for his own life, and all he has for his suffering are sins. Anyone who needs [charity] and inflicts himself with suffering and "bides his time," and lives a life of suffering in order not to burden the community, will not die before acquiring the means to support others. And about him it is said: "Blessed is the man who trusts in Hashem.³⁴Jeremiah 17:7.

Commentary on the the Blessing "Heal us". Containing 1 Se'if:
"Heal us, O God, and we shall be healed..." Even though a verse that is written in the singular may not be modified to the plural [i.e. like the beginning words of this blessing which in Jeremiah 17:14 is written in the singular "heal me"] - this applies in the case when it was intended to be recited [as a verse], but when one says it in the context of a prayer or a request, it is permitted [to modify it]. Gloss: Nevertheless, if one says an entire psalm, it is forbidden to alter it from singular to plural or vice versa. (Tur and the Rosh on the chapter "Hakoreh Omed" [Talmud Megillah 4] in the name of the Ri]

Whosoever is not in need of charity but deceives the public and takes it, will be in actual need before his days are ended. And whosoever is so much in need of charity that he cannot live unless he receive it—as, for instance, a man who is old or sick or in constant pain,—but takes none out of pride, is guilty of blood-shed and is responsible for his own life; so that he has nothing for his suffering, save punishment and sin. But, whosoever is in need of charity and suffers patiently and leads a pinched and humble life, so as not to become a burden to society, will live to help others some day; and it is with reference to such a person that the Bible says, "Blessed is the man that trusteth in the Lord."¹Jeremiah 17:7.
