You shall love the Lord your God with all your mind with all your strength and with all your being. Set these words which I command you this day upon your heart. Teach them diligently to your children. Speak of them when you sit in your house, when you are walking; when you lie down and when you rise up. Bind them as a sign upon your hand; let them be a symbol before your eyes; inscribe them upon the doorpost of your house and on your gates. Be mindful of all My mitzvot and do them; so shall you consecrate yourself unto your God. I, the Lord, am your God who led you out of Egypt to be your G-d; I, the Lord am your G-d.

In 1970 Crosby, Still, Nash and Young brought Deuteronomy to life with their anthem to a generation to Teach Your Children. The song speaks of the need to learn from the past and not repeat mistakes. The song came out as the United States struggled with the Vietnam War. The teaching, however, came straight from Torah, Deuteronomy 11:19.

For Jews, this portion of the Bible is a central part of the weekly Sabbath services and is frequently recited in both Hebrew and English in the Synagogues in the United States. It has become immortalized in newer versions of the Hebrew liturgy. Known as the V'ahavta, the prayer follows the reciting of the watchword of the Jewish faith, the Shemah in which Jews recognize only one God. The V'ahavta compels Jews to remember: 


Train a lad in the way he ought to go; he will  not swerve from it even in old age.

Proverbs  22:6   (JPS)
