What though your treasures are not gold or incense?

Hi,

I am translating a carol song written by an English composer, John Rutter.

There's this sentence ;

What though your treasures are not gold or incense?

I never saw this kind of sentence before. Can someone let me know what this means?

Thank you in advance.

Below is the whole lyrics.

Clear in the darkness a light shines in Bethlehem: Angels are singing, their sound fills the air. Wise men have journeyed to greet their Messiah;But only a mother and baby lie there. 'Ave Maria, ave Maria': Hear the soft lullaby the angel hosts sing. 'Ave Maria, ave Maria, Maiden, and mother of Jesus our King'. Where are his courtiers, and who are his people? Why does he bear neither sceptre nor crown? Shepherds his courtiers, the poor for his people, With peace as his sceptre and love for his crown. 'Ave Maria, ave Maria': Hear the soft lullaby the angel hosts sing. 'Ave Maria, ave Maria, Maiden, and mother of Jesus our King'. What though your treasures are not gold or incense? Lay them before him with hearts full of love. Praise to the Christ child, and praise to his mother Who bore us a Saviour by grace from above. 'Ave Maria, ave Maria': Hear the soft lullaby the angel hosts sing. 'Ave Maria, ave Maria, Maiden, and mother of Jesus our King'.
