“Likewise the Spirit helps us in our weakness; for we do not know how to pray as we ought, but that very Spirit intercedes with sighs too deep for words.

For God Who searches the inmost recesses of the heart can interpret His
own Spirit's meaning. He knows that His
own Will regulates Its petitions, and that they are offered for [His children]
dedicated to His service.
William Sanday & Arthur C. Headlam in A Critical and Exegetical
Commentary on the Epistle to the Romans
