Developing love for Hashem
דבר אל-בני ישראל ואמרת אלהם אדם כי-יקריב מכם קרבן ליקוק וגו’
Speak to the Children of Israel and say to them: “A person, when they [want to] bring an offering to Hashem…”
We find many mitzvos that aren’t outright obligations. Instead, the Torah left it up to the volunteering of the individual. For example, with the donations to the Mishkan, the Torah specified for each person to give as much as they wanted. We also see this by voluntary offerings, such as with the Olah (elevation), Shelamim (peace), or Menachos (flour) offerings. There’s no absolute obligation to bring these offerings, but they’re available for those who want to take advantage. How much terumah a person wants to give to the Kohen is essentially their choice. These types of mitzvos require clarification. If they are part of our Divine service, why weren’t their performance made obligatory, and their quality and quantity well-defined? If they are not part of our Divine service, why are they even taught in the Torah?
