'I Am Your Servant' in the Bible

O Lord, truly I am Your servant;I am Your servant, the son of Your handmaid;You have unfastened my chains.

I am Your servant; give me understanding [the ability to learn and a teachable heart]That I may know Your testimonies.

In your lovingkindness, silence and destroy my enemiesAnd destroy all those who afflict my life,For I am Your servant.
