# a representative offering

The handful of the grain offering represents the whole grain offering. This means the whole offering belongs to Yahweh. 

# It will be an offering made by fire

"It will be a burnt offering" 

# it will produce a sweet aroma for Yahweh

Yahweh being pleased with the sincere worshiper who offered the sacrifice is spoken of as if God were pleased with the aroma of the burning sacrifice.
