וַיֹּ֗אמֶר אֲנִ֨י אַעֲבִ֤יר כָּל־טוּבִי֙ עַל־פָּנֶ֔יךָ וְקָרָ֧אתִֽי בְשֵׁ֛ם יְהוָ֖ה לְפָנֶ֑יךָ וְחַנֹּתִי֙ אֶת־אֲשֶׁ֣ר אָחֹ֔ן וְרִחַמְתִּ֖י אֶת־אֲשֶׁ֥ר אֲרַחֵֽם׃
Ia berfirman: “Aku akan membuat segala kebaikan-Ku lewat di hadapanmu, dan Aku akan menyerukan nama Yang Mahakekal di hadapanmu. Aku akan bermurah hati kepada siapa Aku bermurah hati, dan Aku akan berbelas kasihan kepada siapa Aku berbelas kasihan.”
Rashi
ויאמר אגי אעביר וגו׳ AND HE SAID, I WILL MAKE ALL MY GOODNESS PASS [BEFORE YOU] — The time has arrived when you shall see of My Glory so much as I will allow you to see according as I wish, and therefore I find it necessary to teach you a set form of prayer. Just now when you felt the need to pray for mercy on Israel’s behalf you besought Me to remember the merits of the patriarchs and you thought that if the merits of the patriarchs are exhausted there is no more hope — I will therefore cause all the attribute of My goodness to pass before you on the rock whilst you are placed in the cave.

ויאמר אני אעביר את כל טובי על פניך, “I will let all My goodness pass before you (your eyes) [and identify each attribute of Mine. Ed.] This also is the completion of a subject G-d had already touched upon when He had said, (without specifying) in verse 17: (“I will also grant this wish of yours”). Concerning Moses’ plea to be granted a visual revelation of G-d’s essence, however, He told him that this wish could not be fulfilled as long as his soul was attached to a body; in other words, he would have to wait until after his death. When Moses first heard G-d say that He would not be able to make out G-d’s features, he thought that perhaps G-d thought that he was not sufficiently alert to different features. In order to make clear to Moses that this was not the issue, He immediately told him what He would show him, i.e. from a safe distance when what he would see could not harm him physically; He told him that there was a “place” not far from where His essence was from which he could safely watch if not G-d’s “face” but His “back,” i.e. the result of His having visited that place. G-d’s attributes are recognisable by means of His manifest intervention in His universe and the changes that this intervention will result in. [Some of these words are mine. Editor.] Some scholars interpret this verse differently; they do not understand Moses as having asked to actually “see” G-d with his physical eyes, and they remind us that this same Moses at the burning bush had reacted to a vision of the Divine by hiding his face in fear. (Exodus 3,6) They therefore understand Moses as asking for a visual symbol that his request had been granted. This would serve as a covenant between G-d and himself. As a result, these sages understand Moses’ request as follows: “please show me Your glory by means of concluding a covenant with me, confirming what I requested and Your willingness to grant that request.” G-d consented to doing this, as we know from His saying: “I will let all My goodness pass before your eyes;” this was followed by G-d saying in Exodus 34,10: הנה אנכי כורת ברית נגד כל עמך אעשה נפלאות וגו', “Here I am concluding a covenant with you by displaying miracles in the presence of all of your people, etc. (Rash’bam) אעביר, “I shall proclaim;” We find this root in a similar context in Exodus 36,6, ויעבירו קול במחנה, “they proclaimed loudly throughout the camp, etc.;”

וחנותי את אשר אחון ורחמתי את אשר ארחם, “I will be gracious to whom I will be gracious, and I will be merciful to whom I will be merciful.” I will explain to you the guidelines according to which you will choose which of My attributes to use at a particular time or occasion. However, as to your request for a visual revelation of My Essence, this is not something that can be granted to any living human being at any time.
