Leviticus 1:2

Speak unto the children of Israel, and say unto them, if any man of you bring an offering unto the Lord, ye shall bring your offering of the cattle, even of the herd and of the flock. The sacrifices brought by individuals are described first, voluntary offerings, through which the worshiper intended to draw near to the Lord. The Hebrew word indicates the fact that sinful man, as such, does not dare to draw near to Jehovah. The sacrifice, therefore, is a symbol of his desire to enter into fellowship with Jehovah, and its value consisted in its foreshadowing the greater Sacrifice, through whom we have peace and access to the Father. The voluntary offering was regarded as a gift of the worshiper, no matter whether it was an actual sacrifice or a dedicatory offering. When the individual Israelite had determined to bring such a gift, the Lord's instructions as to the selection of the animal and as to the manner of offering were inclusive and exact.
