Why do Jews touch the metal box and then kiss their fingers when they enter the Synagogue?
The metal container is called a MEZUZAH and we kiss it out of respect for what it contains: a text, central to which is the SHEMA (Hear o Israel the Lord is our God, the Lord is ONE – and thou shalt love the Lord your God with all your heart and all your soul and all your might – and you shall write them on the doorposts of they house and gates (Deut 6,v4-9) which is the profession of faith of a Jews; it also has appended to it the entire commandment as given in the Torah (it is in three sections – Deut 6,4-9; Deut 11, 13-21; and Umbers 15,37-41). As they are in many cases set high up we touch them and then kiss our fingers.
