ROM 8:26

26 And also the Spirit helpeth our infirmity; for what we shall pray, as it behooveth, we know not, but that Spirit asketh for us with sorrowings, that may not be told out. (And the Spirit also helpeth our frailty or weakness; because we do not know what we ought to pray for, or because we do not know how we should pray, but that Spirit asketh for us with groanings, that cannot be told out.)
