Bereshit 2:15 reads: לְעָבְדָהּ וּלְשָׁמְרָהּ, but it seems that this can't be referring to: 'to work the earth and keep it', because after the chet (the sin) it reads in Bereshit 3:23 that Adam was taken out of Eden to work the earth, לַעֲבֹד אֶת-הָאֲדָמָה
The Targums read: and set him to do service in the law, and to keep it('s commandments), while the Zohar points out that l'avdah refers to the positive commandments and uleshomrah to the negative commandments (the do's and don'ts).
But I wondered if there are any scriptures or comments referring to keeping the service, what kind of service was this?
Could Gan Eden be a part of The Heavenly Temple where Adam served and worshiped HaShem?
Hoping for some insight.
