This is also found in the “Apostolic Constitutions” (lib. vii, c. 49), and commences, Εὐλογητὸς εἶ. We give Chatfield’s rendering:

Thou art blessed, O Lord, who nourishest me from my youth,
Who givest food to all flesh.
Fill our hearts with joy and gladness,
That at all times, having all sufficiency,
We may abound to every good work
In Christ Jesus our Lord:
With whom to thee (be) glory, honor, and might,
Forever and ever. Amen.
