Leviticus 1:2

An offering. Heb. qorban, from the verb qarab, “to draw near,” “to approach.” Burnt offerings were of two kinds, obligatory and voluntary. Certain of the obligatory burnt offerings came at stated times and were presented by the priests on behalf of the entire nation. These included the daily burnt offering (Ex. 29:38-42; Num. 28:3–8), the Sabbath burnt offering (Num. 28:9, 10), and festal burnt offerings at the new moon, the Passover, Pentecost, the Feast of Trumpets, the Day of Atonement, and the Feast of Tabernacles (Num. 28:11 to 29:39). Other obligatory burnt offerings were of an occasional nature and were presented by individuals. Such were the offerings at the consecration of a priest (Ex. 29:15-18; Lev. 8:18-21; 9:12-14), at childbirth (Lev. 12:6–8), at the cleansing of a leper (ch. 14:19, 20), at the purifying from ceremonial defilement (ch. 15:14, 15, 30), and at the taking of a Nazirite vow (Num. 6:13-16). Voluntary burnt offerings might be presented by an individual at any time, but must conform in all respects to the same regulations that governed the obligatory burnt offerings (see Num. 7; 1 Kings 8:64). The regulations of Lev. 1 are concerned specifically with voluntary burnt offerings, though the ritual was similar for the others as well.
