How can I form a list of all of Moses prayers.
Welcome to the forums Hans,
First off what you should know is in order to accomplish this task you must have Clause Search functionality. If you have a Base package that supports this then you're in business. Note the screenshot below. To Save the results as a Passage list click the down turning triangle on the Resource Panel and among the drop down list you will see Save As A Passage List select this and you're done. If you need further clarification I will be happy to provide if capable.
Hans, you might also want to see the chart Prayers of Moses in Numbers, which appers in several resources, including the NKJV Study Bible: logosres:nkjvstbib;art=chart.12
If you have Gold or above have a look at "An Exposition on Prayer in the Bible"
Adopting the Basic Search method using search string Moses NEAR prayer I found a resource in my library which was particularly rich in hits, Every Prayer in the Bible. I don't know at what level Base package this resource is included, I have Diamond. But, nevertheless it is relatively affordable for the wealth of information it contains. I include a screenshot for your convenience.
