Psalms Have a Verse Zero

The Book of Psalms places headings and labels at the beginning of 116 out of the 150 Psalms. In Hebrew-based publications of the Tanakh and Psalms, these headings are numbered as verse one. In Christian Bibles, these headings are not numbered. And so, for these 116 Psalms, the verse numbers are off by one as one compares Jewish and Christian printings.
