John Wesley on Hosea 10:1

An empty vine - That hath lost its strength to bring forth fruit. Unto himself - Whatever fruit was brought forth by its remaining strength, was not brought forth to God. His fruit - When the land yielded more plentiful increase, this plenty was employed on multiplying idols. The altars - Of his idols. The goodness - Imagining that the goodness of their land was a blessing from their idols.
