Yahweh being pleased with the sincere worshiper who offered the sacrifice is spoken of as if God were pleased with the aroma of the sacrifice. See how you translated a similar phrase in [Leviticus 1:9](../01/09.md). (See: [[rc://en/ta/man/jit/figs-metaphor]])
The handful of the grain offering represents the whole grain offering. This means the whole offering belongs to Yahweh. See how you translated this in [Leviticus 2:2](../02/02.md).
