Admitting the ability to deny[1]
וכי תזבחו זבח-תודה ליקוק לרצנכם תזבחו
When you bring a thanksgiving offering, you shall offer it willingly[2]
When the Torah instructs us regarding bringing a thanksgiving offering, it tells us to offer it willingly. This is quite surprising, as shouldn’t this be true regarding all offerings? In fact, the Torah tells us[3] in general to bring offerings willingly. Why then does the Torah specify this requirement with thanksgiving offerings?
