וְק֣וֹל ׀ כַּנְפֵ֣י הַחַיּ֗וֹת מַשִּׁיקוֹת֙ אִשָּׁ֣ה אֶל־אֲחוֹתָ֔הּ וְק֥וֹל הָאוֹפַנִּ֖ים לְעֻמָּתָ֑ם וְק֖וֹל רַ֥עַשׁ גָּדֽוֹל׃
還有活物翅膀彼此相碰的聲音，以及在牠們旁邊輪子的聲音，就是極大震動的聲音。

touching Heb. מַשִּׁיקוֹת, an expression of kissing (נְשִּׁיקָה). They would knock one against the other, and a song was heard with their knocking, as he said above (1:24): “And I heard the sound of their wings.”
