וָאָקוּם֮ וָאֵצֵ֣א אֶל־הַבִּקְעָה֒ וְהִנֵּה־שָׁ֤ם כְּבוֹד־יְהוָה֙ עֹמֵ֔ד כַּכָּב֕וֹד אֲשֶׁ֥ר רָאִ֖יתִי עַל־נְהַר־כְּבָ֑ר וָאֶפֹּ֖ל עַל־פָּנָֽי׃
我就起來，出去到平原那裡；看哪，永恆者的榮耀停在那裡，就像我在迦巴魯河邊所見的榮耀一樣；我就俯伏在地。
Rashi
and behold, there the glory of the Lord we standing He went there before me, [thereby demonstrating] a trait of extreme humility, such as is not conventional for a flesh and blood person to practice: [As a rule,] the disciple awaits the Master, whereas here, the Master awaits the disciple.
