  16 G3361 Lest there G5100 be any G4205 fornicator, G2228 or G952 profane person, G5613 as G2269 Esau, G3739 who G473 for G1520 one G1035 morsel of food G591 sold G846 his G4415 birthright.
  17 G1063 For G2467 you know G3754 how that G2532   G3347 afterward, G2309 when he would have G2816 inherited G2129 the blessing, G593 he was rejected: G1063 for G2147 he found G3756 no G5117 place G3341 of repentance, G2539 though G1567 he sought G846 it G1567 carefully G3326 with G1144 tears.
