covenant of circumcision

But beyond the joy that we all feel in the birth of a new baby, the Brit itself has such a special significance to us as individuals and as a people.  Some 4,000 years ago, an old man named Abraham heard the call from  G-d to leave his home and go forward to the Land of Israel.  Some years after his arrival in the land, G-d commanded him to circumcise himself as an act of covenant between him and G-d, an act of covenant that would be repeated by his descendants forever.  At the original covenant with Abraham, G-d changed Abraham’s name from Abram to Abraham.
