Psalms 2:5 - Coke's Commentary on the Holy Bible

Then shall he speak unto them— This denotes, not God's speaking to them by an audible voice; but his making them know, to their full conviction, by the disappointment of their schemes, and the vengeance taken of them, that David was established king in Jerusalem, and should reign in his son the Messiah throughout all generations. For David declares that God would speak to them in his wrath; i.e. by the effects of it; a language the most expressive and convincing of all others. The word בהל bahal rendered vex (in the Margin of our Bibles, trouble,) has a very strong and significant meaning; it implies, that God should put them into the utmost terror, and consternation of mind, and deprive them of all power and ability of soul and body, to save themselves from the vengeance which should be executed on them.
