Let us therefore give diligence (spoudaswmen oun). Volitive subjunctive aorist of spoudazw, old verb to hasten ( 2 Timothy 4:9 ), to be eager and alert ( 1 Thessalonians 2:17 ). The exhortation has a warning like that in Hebrews 4:1 . That no man fall (ina mh pesh). Negative purpose with ina mh and the second aorist active subjunctive of piptw, to fall. After the same example of disobedience (en twi autwi upodeigmati th apeiqeia). The unbelief is like that seen in the Israelites ( Hebrews 3:12Hebrews 3:18 ; Hebrews 4:2 ). Hupodeigma is a late word from upodeiknumi ( Matthew 3:7 ) and means a copy ( John 13:15 ; James 5:10 ). The Israelites set a terrible example and it is so easy to copy the bad examples.
