דברי הימים ב, פרק ל״ה, פסוק ט׳

To ensure the success of the Passover offerings, the leaders of the Levites step forward to make a massive personal contribution. They take it upon themselves to provide for the rest of the Levites, ensuring everyone has what is needed for the sacred event.

Their generous donation consists of two distinct types of animals, each serving a specific purpose. They provide five thousand sheep, which are designated strictly for the main Passover sacrifices. Alongside the sheep, they donate five hundred cattle. These larger animals are meant to serve as the additional festival offerings that accompany the primary Passover sacrifice [ביאור שטיינזלץ].
