Translation Cantate Domino
 
I found the translation of the song text of Cantate Domino sung by Emma Kirkby and Evelyn Tubb.
 
Cantate Domino basically translates "Sing to the Lord"
 
Translation
Cantate Domino canticum novum
cantate Domino ominis terra.
 
Sing to the Lord a new song,
sing to the Lord all the earth.
 
Cantate Domino, et benedicte nomini ejus.
Annuntiate de die in diem salutare ejus.
 
Sing to the Lord and bless his name (give praise);
proclaim (announce) his salvation from day to day.
 
Annuntiate inter gentes gloriam ejus,
in ominbus populis mirabilia ejus.
 
Declare (announce) his glory among the nations,
his wonders among all people.
 
Quoniam magnus Dominus et laudabilis nimis;
terribilis est super omnes deos.

For the Lord is great and greatly to be praised;
he is to be feared above all gods.
