I always like a good prayer. Hannah was barren for years and treated badly by other women. God gave her Samuel and she then gave Samuel to God. This prayer is what she learned through suffering her years of childlessness. By the way, in God's hands her son Samuel made history.

1 Samuel 2:3-7

After Hannah weaned Samuel she let him go to serve God.

“Talk no more so very proudly;
Let no arrogance come from your mouth,
For the Lord is the God of knowledge;
And by Him actions are weighed.

“The bows of the mighty men are broken,
And those who stumbled are girded with strength.

Those who were full have hired themselves out for bread,
And the hungry have ceased to hunger.
Even the barren has borne seven,
And she who has many children has become feeble.

“The Lord kills and makes alive;
He brings down to the grave and brings up.

The Lord makes poor and makes rich;
He brings low and lifts up.
