It is certain that destruction will come from the Almighty because these things have already happened. This can be translated in active form. Alternate translation: "We know this is true because we have already seen the Almighty cut off our supply of food, and he has cut off joy and gladness from the house of our God." (See: [[rc://en/ta/man/translate/figs-ellipsis]] and [[rc://en/ta/man/translate/figs-activepassive]])
You may need to fill in the ellipsis. Alternate translation: "joy and gladness have been cut off from the house of our God" (See: [[rc://en/ta/man/translate/figs-ellipsis]])
These two words mean basically the same thing. Together they emphasize that there is no kind of joyful activity happening at the temple. (See: [[rc://en/ta/man/translate/figs-doublet]])
