Psalms - Songs and prayers expressing worship, lament, and trust in God

In Psalm 131, a Song of Ascents by David, a humble spirit is expressed, discarding proud ambitions and comparing his quieted soul to a weaned child content with its mother.

Lord, my heart is not haughty, nor mine eyes lofty: neither do I exercise myself in great matters, or in things too high for me.

Surely I have behaved and quieted myself, as a child that is weaned of his mother: my soul is even as a weaned child.

Let Israel hope in the LORD from henceforth and for ever.
