נְהָר֥וֹת יִמְחֲאוּ־כָ֑ף יַ֝֗חַד הָרִ֥ים יְרַנֵּֽנוּ׃
Biarlah sungai-sungai bertepuk tangan, biarlah gunung-gunung bersorak-sorai bersama-sama
Rabbeinu Bahya
ומחה על כתף ים כנרת, the word is similar to ימחאו כף, “clapping with one’s hands,” (Psalms 98,8) [i.e. an expression of closeness of two objects, touching].
