There is a funny-sounding Hebrew word that expresses this idea: Yadiyad. You will note that it is two words joined together. The word yad means hand, so the entire word is translated as “hand in hand.” Many ancient cultures believed that one’s heart was in the palm of his hand. So, when you joined hands with someone, you were sharing your heart. Where did the handshake come in? It doesn’t mean much today, but back then, it was a sign of a commitment of friendship, sharing your heart with one another.
