rwp@Hebrews:3:12 @{Take heed} (\blepete\). Present active imperative as in kjv@Phillipians:3:2| (three times) of \blep\ in place of the more usual \horate\. Solemn warning to the Jewish Christians from the experience of the Israelites as told in kjv@Psalms:95|. {Lest haply there shall be} (\m pote estai\). Negative purpose with \m pote\ and the future indicative as in kjv@Mark:14:2|. But we have in kjv@Colossians:2:8| \m tis estai\ as in kjv@Hebrews:12:25|; \m\ occurs with the aorist subjunctive, and \m pote\ with present subjunctive (Hebrews:4:1|) or aorist subjunctive (Acts:5:39|). {In any one of you} (\en tini humn\). The application is personal and pointed. {An evil heart of unbelief} (\kardia ponra apistias\). A remarkable combination. {Heart} (\kardia\) is common in the LXX (about 1,000 times), but "evil heart" only twice in the O.T. (Jeremiah:16:12; 18:12|). \Apistias\ is more than mere unbelief, here rather disbelief, refusal to believe, genitive case describing the evil heart marked by disbelief which is no mark of intelligence then or now. {In falling away from the living God} (\en ti apostnai apo theou zntos\). "In the falling away" (locative case with \en\ of the second aorist active (intransitive) infinitive of \aphistmi\, to stand off from, to step aside from (\apo\ with the ablative case \theou\) the living God (common phrase in the O.T. and the N.T. for God as opposed to lifeless idols)). "Remember that to apostatize from Christ in whom you have found God is to apostatize from God" (Dods). That is true today. See kjv@Ezekiel:20:8| for this use of the verb.
