|Audítam fac mihi mane misericórdiam tuam,*
quia in te sperávi.
|In the morning, make your mercy heard to me,*
for I have hoped in you.
The key here is to grab on to the agreement between misericoridiam tuam and auditam. The verb fac (make, imperative) brings them together: Make your mercy heard. More smoothly we would say: Make me hear your mercy.
