שלשה אש ומים ורוח, אש למעלה ומים למטה ורוח בנתיים, וסימן לדבר שהאש נושאה את המים:

וְאֵ֨לֶּה שְׁמ֤וֹת בְּנֵֽי־ לֵוִי֙ לְתֹ֣לְדֹתָ֔ם גֵּרְשׁ֕וֹן וּקְהָ֖ת וּמְרָרִ֑י וּשְׁנֵי֙ חַיֵּ֣י לֵוִ֔י שֶׁ֧בַע וּשְׁלֹשִׁ֛ים וּמְאַ֖ת שָׁנָֽה׃

And also that every man should eat and drink, and enjoy the good of all his labour, it is the gift of God.

قَالَ يَبْنَؤُمَّ لَا تَأْخُذْ بِلِحْيَتِي وَلَا بِرَأْسِي إِنِّي خَشِيتُ أَنْ تَقُولَ فَرَّقْتَ بَيْنَ بَنِي إِسْرَائِيلَ وَلَمْ تَرْقُبْ قَوْلِي

For even when we were with you, this we commanded you, that if any would not work, neither should he eat.
