Provided each Book starts on a new page, Word can most easily do that if you use a different odd/even page layout, and a set of three STYLEREF fields in each header (left-aligned on odd pages & right-aligned on even pages). The:
• 1st STYLEREF field would reference the Style used for the Book name
• 2nd STYLEREF field would reference the Style used for the Chapter number
• 3rd STYLEREF field would reference the Style used for the Verse number
This, of course, means formatting each Book name, Chapter number & Verse number with Styles that aren't used anywhere else in the document. You might even define Chapter number & Verse number Character Styles just for this purpose. The Book name Style could probably be done using one of Word's Heading Styles.
On the:
• odd pages the STYLEREF fields would each require no switches. The field codes on the odd pages would look like:
{STYLEREF "Book"} {={STYLEREF "Chapter"}-{={STYLEREF "Verse"}-1 \# "1;;0"} \# "0"}:{STYLEREF "Verse"}
• even pages the STYLEREF fields would each require the \l switch. The field code on the odd pages would look like:
{STYLEREF "Book"} {STYLEREF "Chapter" \l}:{ STYLEREF "Verse" \l}
where Book, Chapter & Verse are the Style names.
Note: The STYLEREF field for the even page chapters is enclosed in a formula field. To create that arrangement, all the field brace pairs (i.e. '{ }') for the field coding are created in the document itself, via Ctrl-F9 (Cmd-F9 on a Mac); you can't simply type them or copy & paste them from this message. Nor is it practicable to add them via any of the standard Word dialogues.

See attached demo, which uses the 'Heading 1' Style for the Book names. The Chapter & Verse numbers use 'Chapter' & 'Verse' Character Styles, respectively
