This sterling silver scripture heart necklace encompasses the inscription 'Shema Israel, Eloheinu Echad' in Hebrew which means 'Hear O Israel, the Lord our God, the Lord is one' - Deuteronomy 6:4. These are the first words of what is considered to be the most important Jewish prayer which is recited twice daily, every morning and evening. In the book of Deuteronomy 6:4-9, God commands that the Shema Israel be enclosed in the mezuzah and be worn close to the head and heart. *Please specify length of chain(16" 18 or 20) at the end of your order under "Comments or special requests".
