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.
