34 G3088 The lamp G4983 of the body G2076 is G3788 the eye. G3767 Therefore G3752 when G4675 your G3788 eye G5600 is G573 good, G4675 your G3650 whole G4983 body G2076 is G2532 also G5460 full of light; G1161 but G1875 when G5600 it is G4190 evil, G4675 your G4983 body G2532 also G4652 is full of darkness.

35 G3767 Therefore G4648 see G4648 whether G5457 the light G3588 that is G1722 in G4671 you G2076 G3361 isn't G4655 darkness.

36 G1487 If G3767 therefore G4675 your G3650 whole G4983 body G5460 is full of light, G2192 having G3361 no G5100 G3313 part G4652 dark, G2071 it will be G3650 wholly G5460 full of light, G5613 as G3752 when G3088 the lamp G796 with its bright shining G5461 gives G4571 you G5461 light."
