English: “That you present to Hashem” — valid, and not invalid; from here they said: one who leavens a valid [mincha] is liable, and one who leavens an invalid one is exempt.
In the sugya: The phrase “that you present to Hashem” presupposes an offering that is still fit for presentation.
Type of Learning
Diyuk on asher takrivu — liability attaches only when the minchah is still valid.
What Is Learned
If the mincha has already left the sacred precinct or become tamei, further leavening does not incur the special liability of this prohibition. The Torah’s language presupposes a still-valid offering that one might present.
