Psalms.
131.
A Song of degrees. Of David. Jehovah, my heart is not haughty, nor mine eyes lofty; neither do I exercise myself in great matters, and in things too wonderful for me. 
Surely I have restrained and composed my soul, like a weaned child with its mother: my soul within me is as a weaned child. 
Let Israel hope in Jehovah, from henceforth and for evermore.
