Romans 8:26-27

8:26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. 8:27 And he that searcheth the hearts knoweth what [is] the mind of the Spirit, because he maketh intercession for the saints according to [the will of] God.
