Die - the exchange
The letter tov (ת) is a rosh (ר) with new life springing up. This is confirmed in the transformation of the word am
ar (אמר) into amat (אמת), meaning truth. Truth is the completed word that gives life.

When God warned Adam not to eat the fruit or he would die, skeptics protest: "Isn't that extreme—death for eating a piece of fruit?" "How could Adam understand death if it didn’t yet exist?"
The Hebrew word for "die" is muth (מות), which, like before, is the completed form of mur (מור), meaning "exchange." Death is the final exchange that brings life.
God told Adam that on the day he ate, he would surely undergo this final exchange. What happened? Adam did not die—but the lamb did, providing him with a garment of skin.
This foreshadowed the ultimate exchange: Christ was made to be sin so that we could be made the righteousness of God. We no longer fear death, for even the word itself reveals that it brings life.
