KJV : Ye <5210> are <2075> (5748) of <1537> [your] father <3962> the devil <1228>, and <2532> the lusts <1939> of your <5216> father <3962> ye will <2309> (5719) do <4160> (5721). He <1565> was <2258> (5713) a murderer <443> from <575> the beginning <746>, and <2532> abode <2476> (5707) (5758) not <3756> in <1722> the truth <225>, because <3754> there is <2076> (5748) no <3756> truth <225> in <1722> him <846>. When <3752> he speaketh <2980> (5725) a lie <5579>, he speaketh <2980> (5719) of <1537> his own <2398>: for <3754> he is <2076> (5748) a liar <5583>, and <2532> the father <3962> of it <846>. {of his own: or, from his own will or disposition}
NASB : "You are of \i1 your\i0 father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own \i1 nature,\i0 for he is a liar and the father of lies.
NASB# : <R>"You are of <I>your</I> father<3962> the devil<1228>, and you want<2309> to do<4160> the desires<1939> of your father<3962>. He was a murderer<443> from the beginning<746>, and does not stand<4739> in the truth<225> because<3754> there is no<3756> truth<225> in him. Whenever<3752> he speaks<2980> a lie<5579>, he speaks<2980> from his own<2398> <I>nature,</I> for he is a liar<5583> and the father<3962> of lies<846>.</R>
