Scotland and Israel: what's the connection?

In a few weeks I will travel to Scotland and Israel. So, what's the connection? Not sure, but I am about to find out that is for sure. This is my second trip to Israel and my first to Scotland. While in Scotland, I'll be visiting my ancestor's lands of Gigha ( meaning God's Island), Oronsay (the place of St. Columba who is my ancestor via Nial of the Nine Hostages), Colonsay and Iona. In fact, I'll be in Iona for Easter! Lovely.
