Usage of לָהּ

[Dana]

Why use past tense in the interpretation of והשמש לה, though?
Are there any indications of past tense in the line itself or its context?

By the way, 'her' in לָהּ refers to a fixed instance of אֶרֶץ. The song is essentially a praise and outline of this land.

  There are no indications to show past tense.   Perhaps a better read might be, 'And the sun is to her.'


Yes, makes sense, land being a feminine word.  The song sounds to be creative and beautiful.
