Xi was derived from the Phoenician letter samekh . The numerical value of samekh is 60. His eldest son, Gal (aka James), was the drummer of the Shabbak Samekh band. A letter variant ' takes the place of Samekh at 15th position. Hebrew "samekh" develops a closed cursive form in the middle Hasmonean period (1st century BC). In addition, once the fourth phase is unlocked, Samekh is unsealed. In Talmudic legend, samekh is said to have been a miracle of the Ten Commandments.
