In the haftarah for Behaalotecha/Hanukkah 1 there is an unusual trope for the word zeh in Zekhariah 3:2:
וַיֹּ֨אמֶר יְהוָ֜ה אֶל־הַשָּׂטָ֗ן יִגְעַ֨ר יְהוָ֤ה בְּךָ֙ הַשָּׂטָ֔ן וְיִגְעַ֤ר יְהוָה֙ בְּךָ֔ הַבֹּחֵ֖ר בִּירֽוּשָׁלִָ֑ם הֲל֧וֹא זֶ֦ה א֖וּד מֻצָּ֥ל מֵאֵֽשׁ׃
And the Hashem said unto Satan: 'The Hashem rebuke thee, O Satan, yea, the Hashem that hath chosen Jerusalem rebuke thee; is not this man a brand plucked out of the fire?'
It looks like two commas next to each other. I have asked the teacher at my shul and have listened to some online chantings of the haftarah, and they just make it a tevir, but it's not. I found one online site calling it a mercha kefula but the attached audio is for its chanting in a Torah reading, not haftarah. Does anyone know how to chant it for haftarah?
