Reference for Megillah 58:19

בשלמא למ"ד כי תשא היינו דמתרמי בההוא זימנא

This works for the one who holds that “When you count” is read because [the regular portion containing this passage] falls about that time. But according to the one who says that “Command…My sacrifice” does [the portion containing that passage] fall about that time?
