Adam Clarke Bible Commentary

The land itself vomiteth out her inhabitants - This is a very nervous prosopopoeia or personification; a figure by which any part of inanimate nature may be represented as possessing the passions and reason of man. Here the land is represented as an intelligent being, with a deep and refined sense of moral good and evil: information concerning the abominations of the people is brought to this personified land, with which it is so deeply affected that a nausea is produced, and it vomits out its abominable and accursed inhabitants. It was natural for the inspired penman to make use of such a figure, as the description he was obliged to give of so many and enormous abominations must have affected him nearly in the same way in which he represents the land to be affected.
