Alessandro Scarlatti,
Exaltabo te Domine

The Offertory for both Ash Wednesday and the Eleventh Sunday after Trinity is a text from Psalm 30:

Exaltabo te Domine, quoniam suscepisti me
I will magnify thee, O Lord, for thou hast set me up:
nec delectasti inimicos meos super me.
and not made my foes to triumph over me.
Domine clamavi ad te et sanasti me.
O Lord my God, I cried unto thee: and thou hast healed me.

Alessandro Scarlatti (1660-1725) is best known for his operas, but he also composed choral music for liturgical use, including a setting of this Offertory text. It is sung here by the Pro Arte Singers (New Canaan, CT), directed by Arthur Sjogren.
