Webster_Strongs(i)
  12 G1161 Now G2249 we G2983 [G5627] have received G3756 , not G4151 the spirit G2889 of the world G235 , but G4151 the Spirit G3588 who G1537 is from G2316 God G2443 ; that G1492 [G5762] we may know G5483 [G5685] the things that are freely given G2254 to us G5259 by G2316 God.
  13 G3739 Which things G2532 also G2980 [G5719] we speak G3756 , not G1722 in G3056 the words G442 which man's G4678 wisdom G1318 teacheth G235 , but G40 which the Holy G4151 Spirit G1722 G1318 teacheth G4793 [G5723] ; comparing G4152 spiritual things G4152 with spiritual.
  14 G1161 But G5591 the natural G444 man G1209 [G5736] receiveth G3756 not G3588 the things G4151 of the Spirit G2316 of God G1063 : for G2076 [G5748] they are G3472 foolishness G846 to him G2532 G3756 : neither G1410 [G5736] can G1097 [G5629] he know G3754 them, because G4153 they are spiritually G350 [G5743] discerned.
