עזרא, פרק ז׳, פסוק י״ז

The King of Persia issues clear, practical instructions to Ezra regarding the wealth gathered for the Temple. Because a large amount of money has been collected, the king commands Ezra to act quickly and efficiently to purchase everything needed for the sacrifices [רש"י, מצודת דוד, רס"ג, אבן עזרא, ביאור שטיינזלץ]. The required items include specific animals, namely bulls, rams, and sheep. In addition to the livestock, the funds must be used for the accompanying meal offerings and libations, which consist of fine flour and wine [אבן עזרא, מצודת דוד, ביאור שטיינזלץ]. Once purchased, these are to be brought and offered on the altar in the House of God in Jerusalem [רס"ג, רש"י].

The distinct focus on purchasing sacrifices clarifies that this is the primary and most important purpose of the donated funds. Any silver and gold left over after securing the sacrifices can then be used for other permitted Temple needs according to Jewish law. However, the actual vessels used for the service must remain completely intact and be dedicated exclusively to the holy work [מלבי"ם].
