Leviticus 2 gives the grain offering from the offerer's perspective; Leviticus 6 adds priestly eating rules and distinguishes the priest's own wholly burned grain offering. Reading both sections together shows one offering from two angles: what the worshiper brings and what the priests do with the memorial and remaining portion.

Leviticus 2 explains prepared grain offerings from the worshiper’s perspective, including baked, griddle, and pan forms. Leviticus 6 explicitly returns to the grain-offering law and gives priestly handling and eating instructions. The later section therefore completes the same offering system by describing what the priests do with the portion not burned on the altar.

Paul explicitly appeals to the fact that those who serve at the temple/altar share in sacrificial provisions when arguing for support of gospel workers. Leviticus 6 is part of the Torah background for that priestly provision.
