I found the song : the Lord is my shepherd .... But really , if you find another version , I wouldn't mind ... This one is sinister and really seems made for a funeral ... I found versions with only the music ... Well, maybe you'll find some inspiration, or you can ask for help to your music teacher ... I am hopeless at singing -although I like it
Bye for now , try to learn your part
See you
Teach

The last one seems the easiest , it might be a good exercise ... Well, there are several versions on the right of the page ...
This is just an English exercise , it happens to be related to religion , but it is not my aim ....
