What do the "Numbers Main", "Numbers Left", and "Numbers Right" options do?|
Some languages use a different numbering system than the 1,2,3 of European languages. The Numbers option lets you see the chapter and verse numbers in a different number system.
Numbers Main controls what number system will be used to for the chapter and verse numbers that are displayed as headers.
If you have selected Verse on Top from the Display Format list, then only Numbers Main will matter for you.
Numbers Left controls what number system will be used for the verse numbers on the left side of each verse (only if Verse on Side is selected).
Numbers Right controls what number system will be used for the verse numbers on the right side of each verse (only if Verse on Side is selected). If Default is selected, verse numbers will only show on the right if a right-to-left language like Syriac or Arabic is being displayed.
