But watch ye (agrupneite de). Agrupnew is a late verb to be sleepless (a privative and upno, sleep). Keep awake and be ready is the pith of Christ's warning. That ye may prevail to escape (ina katiscushte ekpugein). First aorist active subjunctive with ina of purpose. The verb katiscuw means to have strength against (cf. Matthew 16:18 ). Common in later writers. Ekpugein is second aorist active infinitive, to escape out. To stand before the Son of man (staqhnai emprosqen tou uiou tou anqrwpou). That is the goal. There will be no dread of the Son then if one is ready. Staqhnai is first aorist passive infinitive of isthmi.
