The extent of your grain harvest becomes clear only when you present it all in one towering pile. Each grain present in that golden mountain represents a day of labor—the taller the pile, the greater the extent of your effort.
Additional thoughts
Visualize a massive grain pile being presented before village judges who measure its height to determine the extent of a farmer's season. Height equals degree, scope, extent.

Present your grain pile to reveal the extent of your harvest.
