Francis,
Verses 2-6 are all NV, but it's a 1696 text of the NV (as shown at https://archive.org/stream/newversal00brad#page/3/mode/1up), rather than one including some of the textual variants which later became more commonly used.

I can't bring to mind any other examples of 'mixing' verses from different metrical versions in the way Smyth and NV are combined here.

Regards,
Edmund.
