וְהָיָה֙ אֲר֣וֹן יְהוָ֔ה בָּ֖א עִ֣יר דָּוִ֑ד וּמִיכַ֨ל בַּת־שָׁא֜וּל נִשְׁקְפָ֣ה ׀ בְּעַ֣ד הַחַלּ֗וֹן וַתֵּ֨רֶא אֶת־הַמֶּ֤לֶךְ דָּוִד֙ מְפַזֵּ֤ז וּמְכַרְכֵּר֙ לִפְנֵ֣י יְהוָ֔ה וַתִּ֥בֶז ל֖וֹ בְּלִבָּֽהּ׃
Ketika tabut Yang Mahakekal masuk ke Kota Daud, Mikhal anak perempuan Saul menjenguk dari jendela, lalu melihat Raja Daud melompat-lompat dan menari-nari di hadapan Yang Mahakekal. Maka ia memandang rendah Daud di dalam hatinya.
Rav Hirsch
פזז .ויפוו זרועי ידיו: einerseits מפַנֵן ומכרכר (Sam. II. 6, 16) eine außerordentliche Kraftäußerung, andererseits: כלי פז ,עטרת פז, sehr wertvolles Gold; die Verwandtschaft dieser Bedeutungen ist dunkel.
Radak
ויפוזו זרעי ידיו, his hands and arms kept getting stronger, i.e. he acquired the means to punish those who had slandered him. We encounter the expression מפזז in Samuel II 6,16 as a description of strength. It appears there next to the word מכרכר, a variation of the root פזז having a similar meaning, when applied to the legs. What was the source of Joseph’s strength?
Rashbam
ויפוזו, leaping in a wild dance, as in Samuel II 6,16. Here the expression is applied to Joseph’s hand, arms. In Samuel the word כרכר describes parallel motions with the legs. The image conveyed by the word is that of twirling one’s limbs.
