A homer of seed shall yield what according to Isaiah 5:10?

The correct answer is one ephah. This verse, Isaiah 5:10, is significant because it illustrates the judgment and the extreme decline in agricultural productivity that will accompany the destruction of the land due to the people's sins. A homer is a large measure of capacity, and in this context, it indicates that a homer of seed—normally expected to produce a much greater yield—will result in only one ephah. An ephah is a smaller measure than a homer, emphasizing the scarcity that will follow. This imagery serves to highlight the consequences of the people's unfaithfulness and the resulting desolation of the land. The association of large expectations with minimal yield creates a stark contrast, enhancing the prophetic warning.
