I suggest checking out James Gelvin's "The Teaching Company" lectures on the topic. Also consider watching the "50 Years War" documentary, which goes to pretty much the start of the current conflict (since the conflict doesn't actually go for 2,000 years like people like to say). Also consider reading Smith's book Palestine and the Arab-Israeli Conflict, which is pro-Palestine, alongside Righteous Victims by Benny Morris, which will give you a pro-Israeli view. If you'd like briefer books that also touch on ancient times, then Harms' The Palestine-Israel Conflict: A Basic Introduction and Israel: A Brief History (pro-Palestine and pro-Israel slants) are good, general overviews to read alongside the above.
