God's Name in the Hebrew Bible: Yahweh, Jehovah & Adonai

I was lecturing to a group of students at a Christian University and one of the students asked me about God's name in the Hebrew Bible. Is it Yahweh, is it Jehovah? This video an excerpt from my lecture. I put my notes aside and explain the popular pronunciations of God's name and the Jewish tradition of not pronouncing the four-letter name.
