The Sh’ma is probably one of the most significant Jewish prayers.
It comes from the book of Deuteronomy, chapter 6, verse 4.
I extended it, as shown below. The original song is printed in purple.
Sh’ma, Yisrael! Adonai elohenu. Adonai ekhad.
Listen, Israel! The Lord is our God. The Lord is one.
Ba-rukh Shem k’vod malkhuto, l'olam va-ed.
Blessed is our God’s glorious majesty, forever and ever.
I love my God with all my mind and resources, all my strength and might.
I love my God with all my life, all my being, all my heart and soul.
