Matthew Poole and continuators on Psalms 94:4

4 How long shall they utter , and speak hard things ! and all the workers of iniquity boast themselves .

Or pour forth freely, constantly, abundantly, as a Fountain doth Waters, as this Hebrew word signifies.

Grievous and insolent and intolerable words against thee and thy people, blasphemous, malicious, contemptuous and minatory words.

Boast of their invincible power and prosperous success in their wicked designs.
