NET
26 In the same way, the Spirit helps us in our weakness, for we do not know how we should pray, but the Spirit himself intercedes for us with inexpressible groanings.
Darby
26 And in like manner the Spirit joins also its help to our weakness; for we do not know what we should pray for as is fitting, but the Spirit itself makes intercession with groanings which cannot be uttered.
KJV
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.
