Leviticus 2 outlines the regulations for grain offerings, a type of voluntary offering to God. These offerings, made from fine flour, could be presented in various forms: unbaked flour mixed with oil and frankincense, baked cakes (oven-baked, griddle-cooked, or pan-fried) with oil, or crushed heads of new grain. A portion, mixed with oil and all the frankincense, was burned on the altar as a "memorial portion" to produce a pleasing aroma to the Lord. The remainder was given to the priests for their consumption. Key rules include using unleavened flour, adding salt to all offerings (symbolizing the covenant), and prohibiting leaven and honey, though fresh grain could be offered roasted. These offerings expressed gratitude and devotion to God.
