Another texted duet borrows from the Magnificat. "Fecit potentiam . . ." is in KJV "He hath shewed strength with his arm; he hath scattered the proud in the imagination of their hearts" Luke 1:51. Here a short first phrase ("Fecit potentiam") is without cadence, but the second is very clear (for "in brachio suo"), involving three thirds and two 2-3 bass suspensions.
The conclusion again is the point of interest, however: now familiar rising gestures in connection with a 6-8 cadenza perfetta, but note that the approach in the upper voice is repeated, a less likely option than a more varied, but still mainly stepwise figure.
