Psalm 37/Notes/Lexical.vv. 1-2.59527
From Psalms: Layer by Layer
v. 2a: The adverb מְהֵרָה probably refers to the imminence of the wicked's destruction as well as to the speed with which it will take place. It will happen "soon" (NIV, NLT, ESV, CEV, GNT), and when it does, it will happen "quickly" (NET). Cf. v. 10.
