Exodus 33:5

רגע אחד אעלה בקרבך וכליתיך WERE I TO GO UP AMONG THEE ONE MOMENT, I SHOULD CONSUME THEE — If I were to go up amongst you and you rebelled against Me in your stiff-neckedness I would be angry with you but one moment — for this is the duration of His wrath (Berakhot 7a), as it is said, (Isaiah 26:20) “Hide thyself for a short moment, until the indignation be passed” — and I would consume you; therefore it is better for you that I should send an angel. ועתה AND NOW — This punishment shall be inflicted upon you now, at once, viz., that you should put off your ornaments from you. ואדעה מה אעשה לך AND I KNOW WHAT I SHALL DO UNTO THEE — In respect to the visitation for the remainder of the sin which still remains unpunished (cf. Rashi on Exodus 32:34) I know what is in My mind to do unto you.

וַיֹּ֨אמֶר יְהֹוָ֜ה אֶל־מֹשֶׁ֗ה אֱמֹ֤ר אֶל־בְּנֵֽי־יִשְׂרָאֵל֙ אַתֶּ֣ם עַם־קְשֵׁה־עֹ֔רֶף רֶ֧גַע אֶחָ֛ד אֶֽעֱלֶ֥ה בְקִרְבְּךָ֖ וְכִלִּיתִ֑יךָ וְעַתָּ֗ה הוֹרֵ֤ד עֶדְיְךָ֙ מֵֽעָלֶ֔יךָ וְאֵדְעָ֖ה מָ֥ה אֶֽעֱשֶׂה־לָּֽךְ׃

For the Lord had said to Moshe, Say to the children of Yisra᾽el, You are a stiffnecked people: I will come up into the midst of thee for a moment and consume thee: therefore now put off thy ornaments from thee, that I may know what to do to thee.
