Hmm...

    Do not gaze at me because I am dark,
    because the sun has looked upon me.
    My mother's sons were angry with me;
    they made me keeper of the vineyards,

suggests another layer to:

    Там смуглянка-молдаванка
    Собирала виноград.

    there's a dark-skinned moldavian girl
    harvesting the grapes
