Leviticus 1
Leviticus opens with God speaking from the tent of meeting — the tabernacle now fully installed — to give Moses the burnt offering regulations. The burnt offering (olah) is the offering of total consecration: the entire animal is consumed on the altar, nothing withheld. Three categories of animals are permitted — cattle, sheep or goats, and birds — with the quality standard (male without defect) consistent across all, while the cost scales downward to ensure that every Israelite, regardless of wealth, can participate. The offerer lays hands on the animal, identifying with it before slaughtering it; the priests splash the blood on the altar. The pleasing aroma formula closes each category, communicating that the completeness of the offering — not the cost — is what produces the Lord's acceptance. Hebrews 10:10 says Christ's total self-offering fulfills what the burnt offering could only foreshadow.
