"My offering, My bread" (Numbers 28:2). The sacrifices are compared to bread. Just as food draws and brings life from the soul into the body, so too the service of the sacrifices draws Divine abundance into the worlds.
(Alter Rebbe, Likkutei Torah)
"The one lamb shall you offer in the morning, and the other lamb shall you offer in the afternoon" (Numbers 28:4). Both in times of “morning” – times of joy, and in times of “afternoon” – difficult times, one must remain consistent in the sacrificial service, meaning, in striving to draw near to G-d and cleave to Him.
(the Rebbe)
“A continual burnt offering, as the one offered at Mount Sinai” (Numbers 28:6). In the Talmud tractate Menachot we are taught: When the Temple no longer stands, one who reads the section of sacrifices is considered as if they offered a sacrifice. For this reason, we recite the tamid (daily sacrifice) passage every day. This is hinted in the phrase “a continual burnt offering”—how can it be offered continually when there is no Temple? The verse continues: “as the one offered at Mount Sinai”—through Torah study, which was given at Sinai.
(Mikra Meforesh)
Entirely for G-d
The tamid (daily) offering, which symbolizes all the sacrifices, was an olah (burnt offering)—completely consumed by fire, entirely for G-d. This teaches us that if we desire true closeness with G-d—korban (sacrifice) sharing the same Hebrew letters as kiruv (closeness)—we must serve Him in the manner of “entirely for G-d”, not in order to receive a reward.
