May my nourishment and the nourishment of my household,
of my offspring and the children of my offspring,
be committed to Your Hand, and not subject to mortal hands

Could either of these be what you are looking for?

"The Standard Prayer Book is an American reprint of The Authorized Daily Prayer Book, which is in general use today throughout the British Empire. It was originally published under the authorization of the late Chief Rabbi, Dr. Nathan Marcus Adler. The English translation, by the Rev. Simeon Singer, is universally acknowledged to be the best ever published. This American edition is set from new and larger type and is characterized by the continuity of the text, which has necessitated the addition of nearly 300 pages, making it the most complete daily prayer-book ever published."

"{p. 427}"

"Have mercy, O Lord our God, upon Israel thy people, upon Jerusalem thy city, upon Zion the abiding place of thy glory, upon the kingdom of the house of David thine anointed, and upon the great and holy house that was called by thy name. O our God, our Father, feed us, nourish us, sustain, support and relieve us, and speedily O Lord our God, grant us relief from all our troubles. We beseech thee, O Lord our God, let us not be in need either of the gifts of flesh and blood or of their loans, but only of thy helping hand, which is full, open, holy and ample, so that we may not be ashamed nor confounded for ever and ever."

{p. 468}

"And now, O good and beneficent God, what shall we say, what shall we speak unto thee? Our needs are many, our knowledge slender. Shame covers us as often as the remembrance of all thy love for us rises within our minds. O turn this day in lovingkindness and tender mercy to the prayers of thy servants who pour out their souls before thee. May thy lovingkindness not depart from us. Give us our needful sustenance, and let us not be in want of the gifts of flesh and blood. Remove from us care and {sic "sorow" "sorrow"}, distress and fear, shame and contempt. Let thy grace be with us, that we may rear our children to keep thy commandments and to fulfil thy will all the days of their life. O God, take us not hence in the midst of our days. Let us complete in peace the number of our years. Verily we know that our strength is frail, and that thou hast made our days as handbreadths. Help us, O God of our salvation, to bear ourselves faithfully and blamelessly during the years of our pilgrimage. And when our end draws nigh and we depart this world, be thou with us, and may our souls be bound up in the bond of life with the souls of our parents and of the righteous who are ever with thee. Amen, and Amen."
