Shemos 30:12

כִּ֣י תִשָּׂ֞א אֶת־רֹ֥אשׁ בְּנֵֽי־יִשְׂרָאֵל֮ לִפְקֻדֵיהֶם֒ וְנָ֨תְנ֜וּ אִ֣ישׁ כֹּ֧פֶר נַפְשׁ֛וֹ לַיהֹוָ֖ה בִּפְקֹ֣ד אֹתָ֑ם וְלֹא־יִהְיֶ֥ה בָהֶ֛ם נֶ֖גֶף בִּפְקֹ֥ד אֹתָֽם

“When you take a census…”

In the Ba’al HaTurim: Pekudim (countings) appears three times; Machatzis HaShekel (half-shekel) appears three times; Kofer Nafsho (atonement for his soul) appears three times; Lichaper (to atone) appears three times; and Bnei Yisrael (Children of Israel) appears three times.

It should be said that these five correspond to the five things that occurred during the act of the [Golden] Calf:

1. They ate 2. And they drank 3. And they rose up to make merry 4. And they prostrated themselves 5. And they sacrificed.

And corresponding to this, they also brought five types of gold for the donation of the Tabernacle, as it is written later (35:22): Brooch (Chach), earring (Nezem), ring (Taba’as), body-ornament (Kumaz), and gold vessels (Klei Zahav). See further (32:17) in the Ba’al HaTurim
