"Which cannot be uttered"

1. Rom. 8: 26
   26 Likewise the Spirit also ^ahelpeth our infirmities: for we know not what we should ^bpray for as we ought: but the Spirit itself maketh ^cintercession for us with ^dgroanings which cannot be uttered.
2. Hel. 5: 33
   33 And also again the third time the voice came, and did speak unto them marvelous words which ^acannot be uttered by man; and the walls did tremble again, and the earth shook as if it were about to divide asunder.
