The Value of Every Jew After the Tochachah

After the tochachah, the Torah teaches the laws of ערכין, which is when a person says עלי ערכי, "I will give my worth to the Beis HaMikdash," or עלי פלוני ערך, "I will give the worth of another person to the Beis HaMikdash." According to age and gender, the Torah dictates the monetary ערך, worth, which he must pay. Why do these halachos follow the tochachah?

The Chozeh of Lublin zt'l explains that after reading the tochachah, one might think Hashem is angry with him. He might feel worthless. Therefore, following the tochachah comes the parashah of ערכין to remind us that all Bnei Yisroel have tremendous worth and value before Hashem.
