Stupor - Vine's Expository Dictionary of New Testament Words
Stupor
[ 1,,G2659, katanuxis ]a pricking" (akin to katanusso, "to strike" or "prick violently," Acts 2:37), is used in Romans 11:8, RV, "stupor" (AV, "slumber"). It is suggested that this meaning arose from the influence of the verb katanustazo, "to nod" or "fall asleep" (Field, Notes on the Translation of the NT). Evidently what is signified is the dulling of the spiritual sense. In the Sept., Psalms 60:3; Isaiah 29:10.
