Don't worry, there are several ways to handle page losses and at least you know what the missing text says!
Really thin Bible pages when they are all torn up like this need to be lined on one side with a tissue that is see-through. While you can use Japanese tissue and paste to do this, it is not an easy procedure for a beginner. Instead, I recommend using heat-set tissue which means you basically iron the tissue on to the paper.
I can see that I will have to make a course on this. Here is a summary of steps
Never iron directly onto an original item. Iron through baking parchment /silicone release paper!
Cut a piece of heat-set tissue (comes in a roll sometimes) to be a bit bigger than the text-block dimensions.
Tack (touch the iron to it in a couple of spots - so it activates the adhesive) the page to it. You are going to attach it on the VERSO side unless there is an illustration to avoid.
For the chunks that are missing you can re-create them and print them out onto Sekishu tissue. This will take time to figure sizes and fonts but it can be done.
Use the Shadow Tracer (from the page repair kit) to trim them to the right sizes and paste the edges of them to apply then iron to activate the heat-set tissue.
You can use heat-set tissue on the recto side to fill in any blank losses.
Trim the inner hinge area and then attach to the text-block. Trim the other 3 sides after it is in place.
I can't tell you the number of times I have trimmed first and then found my measurements to be off.
Another option is to replace the page with a copy from another book. This would be discarding original materials so consider if that is important to you. Also it is harder than you think to find an exact copy. Different editions may have different words on the same page or be a different size.
Always make a note that it is a facsimile page either when you sell it or better yet, just write in pencil on the page itself in the lower inner verso side corner.
