The moving story of Hannah appears in the first and second chapter of Samuel I: Hannah had no children, and she begged Hashem in the holy tabernacle at Shilo that if He gives her a child, she will dedicate this child to the service of Hashem. Hashem heard her prayers, and Samuel was born.
When Samuel was weaned, Hannah brought him to the High Priest Eli in Shilo, where the little Samuel grew up devoting his entire life to serving Hashem. As Hannah presents her son to Eli, she says, "This is the lad I prayed for; Hashem granted me the request that I asked of Him" (Samuel I, 1:27).
In a beautiful age-old Jewish tradition, when we check on our sleeping children at night, and we see them like little angels fast asleep, we repeat the above passage as an expression of gratitude to Hashem, and we continue to pray for their spiritual and physical welfare and development.
Shraga Gold, soloists Motty Steinmetz, Levi Falkowitz, Moshe Mendlowitz and the Shira Choir sing Rabbi Shlomo Yehuda Rechnitz's lovely rendition of Hannah's moving expression of gratitude in the following beautiful clip, which we hope you enjoy as much as we did. G-d bless and much joy from your children!
