ترجمه - لاتین-انگلیسی - cantate domino canticum novum, aleluja, aleluja,...

"Hallelujah" and "chant" are solemner, aren't they?

in your translation it's difficult to understand if "the whole earth" is the subject or the object

I agree. I believe 'omnis terra' is subject here for it is written in the nominative case. The translation doesn't make that entirely clear.

Hi. I don't know, you may be right, but I don't see like that.I don't believe "omnis terra" is the subject here.

My interpretation is this : (You)sing to the Lord (about) the whole world.

not

The whole world sings to the Lord...
