Quote of the Evening - John Donne

This is the xxiii stanza of John Donne's "A Litany". I'm interested in the doubled action of prayer in the last line.

Hear us, O hear us, Lord; to Thee
A sinner is more music, when he prays,
Than spheres' or angels' praises be,
In panegyric alleluias ;
Hear us, for till Thou hear us, Lord,
We know not what to say ;
Thine ear to our sighs, tears, thoughts, gives voice and word;
O Thou, who Satan heard'st in Job's sick day,
Hear Thyself now, for Thou in us dost pray.
