Some short verses contain only members of the sof passuk group.
[2] Different melodies are assigned to the trope for each section of the Hebrew Bible: The Torah, the Haftarah, and the Megillot.
There is controversy over the use of the sof passuk during the reading of the Ten Commandments.
There are two versions of the trope sounds for the Ten Commandments, one that divides them into 13 verses, based on the number of sof passuk notes, and the other that divides them into ten verses, the actual number of commandments.
It is for this reason that not all commandments actually have a sof passuk at the end of their own names.
