Psalms 95:4

In his hand; under his government. The deep places; those parts which are far out of men's sight and reach, and much more those that are at men's disposal. The strength of the hills; the strongest or highest mountains are under his feet, and at his disposal. The sense of the verse is, All the parts of the earth, whether high or low, are subject to his power and providence, and therefore it is not strange if all the nations of the earth be brought to the acknowledgment of him, and if the Gentiles receive his gospel.
