女 at the bottom is the indexing radical, a kneeling figure with crossed arms, the classical pose of yielding. With the bowed grain above, the whole picture is a person stooping in deference, the source of 'to entrust, delegate, winding'.
禾 on top is a grain pictograph, a stalk drooping under ripe ears. Here it pictures a bowed head: heavy grain bending down is the visual metaphor for yielding and entrusting that powers the deferential senses of 委.
