The verse I am focusing on and translating for you is the last one. The soprano sings it very simply by herself in the video below, while other verses are sung by congregation or ensemble:
"Ach ich bin viel zu wenig, zu ruehmen seinen Ruhm; der Herr allein ist Koenig, ich eine welke Blum. Jedoch weil ich gehoere gen Zion in sein Zelt, ist's billig, dass ich mehre sein Lob vor aller Welt."
"Oh, I am much too small to praise his glory;
the Lord alone is king, I am a wilting flower.
Yet--since I belong to Zion in his tent--
it is right that I contribute to his praises before the entire world."
