ASV_Strongs(i)
  20 G80 Brethren, G1096 be G3361 not G3813 children G5424 in mind: G235 yet G2549 in malice G3515 be ye babes, G1161 but G5424 in mind G1096 be G5046 men.
  21 G1722 In G3551 the law G3754 it is written, G1722 By G2084 men of strange tongues G2532 and G1722 by G5491 the lips G2087 of strangers G2980 will I speak G5129 unto this G2992 people; G2532 and G3761 not G3779 even thus G1522 will they G1522 hear G3450 me, G3004 saith G2962 the Lord.
  22 G5620 Wherefore G1100 tongues G1526 are G1519 for G4592 a sign, G3756 not G3588 to them G4100 that believe, G235 but G3588 to the G571 unbelieving: G1161 but G4394 prophesying G571 is for a sign, not G3588 to the G571 unbelieving, G235 but G3588 to them G4100 that believe.
