Matthew Poole and continuators on Psalms 104:32

32 He looketh on the earth, and it trembleth; he toucheth the hills, and they smoke .

This is a further illustration of Gods powerful Providence over all the Creatures, and their dependence upon him: As when he affords his favour to Creatures, they live and thrive, so on the contrary one angry look or touch of his upon the Hills or Earth, makes them tremble and smoke, as once Sinai did when God appeared in it. And this consideration he may possibly suggest to inforce the foregoing exhortation of glorifying God, because if we do not give him the glory due to his name, he can quickly right himself and destroy us and all his works.
