The rules of trup, pg vi

The Rules of Trup by Wolf Heidenheim continues. See previous segment. He concludes his discussion of whether or not segolta is a melech, and turns to pasek. He says it is not, and even though you see the same vertical bar in the munach legarmeih, that is a different trup. And he explains away the seeming exception. The text of his work follows:

for one instance in Scriptures where the segolah does not come after it, and it is (Yeshaya 45:1)*

כֹּֽה־אָמַ֣ר יְהוָה֮ לִמְשִׁיחוֹ֮ לְכ֣וֹרֶשׁ | אֲשֶׁר־הֶֽחֱזַ֣קְתִּי בִֽימִינ֗וֹ לְרַד־לְפָנָיו֙ גּוֹיִ֔ם וּמָתְנֵ֥י מְלָכִ֖ים אֲפַתֵּ֑חַ לִפְתֹּ֤חַ לְפָנָיו֙ דְּלָתַ֔יִם וּשְׁעָרִ֖ים לֹ֥א יִסָּגֵֽרוּ׃

{see Wickes' discussion of this pasuk here.} {The trup at mechon-mamre lacks the vertical bar which would clearly mark this as munach Legarmeih.}
and sometimes two zarkas come one after the other, and a single segolah comes after them, such as (I Shmuel 2:15)

גַּם֮ בְּטֶרֶם֮ יַקְטִר֣וּן אֶת־הַחֵלֶב֒ וּבָ֣א ׀ נַ֣עַר הַכֹּהֵ֗ן וְאָמַר֙ לָאִ֣ישׁ הַזֹּבֵ֔חַ תְּנָ֣ה בָשָׂ֔ר לִצְל֖וֹת לַכֹּהֵ֑ן וְלֹֽא־יִקַּ֧ח מִמְּךָ֛ בָּשָׂ֥ר מְבֻשָּׁ֖ל כִּ֥י אִם־חָֽי׃

And so too the Pasek is not counted either with the teamim nor the meshartim. It is not enumerated with the teamim for it only comes with the mesharet, such as Divrei Hayamim I 21:3:
וַיֹּ֣אמֶר יוֹאָ֗ב יוֹסֵף֩ יְהוָ֨ה עַל־עַמּ֤וֹ ׀ כָּהֵם֙

and we said above that this {cantillation mark on amo, before the pasek} shofar mahpach is of the mesharetim. And further, in Bereishit 18:21,
עָשׂ֣וּ ׀ כָּלָ֑ה
which is a shofer illui, which is from the mesharetim.

And if a person whispers to you that "does not the legarmeih come with a shofar?" {That is, it is a munach sign followed by a pasek sign.} This is its way, that you never find a legarmeih except with a shofar and a {vertical} stroke between two words, and all legarmeihs in Scripture come before a revia, such as (Devarim 31:20)
כִּֽי־אֲבִיאֶ֜נּוּ אֶֽל־הָאֲדָמָ֣ה ׀ אֲשֶׁר־נִשְׁבַּ֣עְתִּי לַֽאֲבֹתָ֗יו
except for in a few places which are enumerated in this work, in the gate of legarmeih. And {meanwhile}, pasek is never found before revia (in the middle of a verse) except for in one place in Scriptures, which is (Yeshaya 42:5)
כֹּֽה־אָמַ֞ר הָאֵ֣ל ׀ יְהוָ֗ה בּוֹרֵ֤א הַשָּׁמַ֨יִם֙

* {As I noted above, our standard trup is different than he gives above. He explains:} So is the melody of this verse in manuscripts and careful version, and so is primary {what is should be}: Koresh with a munach legarmeih, for we never place two munachs to a revii if the first one is not a munach legarmeih, as is explained later on in the second gate, chapter one, in the law of revii.
