I suppose your question could be referring to the 1982 Lebanon War. Israeli Defense Force invaded southern Lebanon, seeking to oust the Palestine Liberation Organization from the region. They did so and established an Israeli security zone in that region.

I think it more likely, though, that your question refers to the 2006 Lebanon War, also sometimes referred to as the 2006 Israel-Hezbollah War or (in Israel) as the Second Lebanon War. That conflict got started when the Hezbollah group carried out raids across the border into Israel in July, 2006. In the raids, they abducted two Israeli soldiers and took them into Lebanon. Other Israeli soldiers died in a failed rescue attempt. Hezbollah used their prisoners to demand release of Lebanese prisoners held by Israel in exchange. Israel wouldn't do that, and attacked with airstrikes and artillery against Hezbollah strongholds in Lebanon. Israeli Defense Forces also launched a ground invasion into Southern Lebanon and imposed a blockade of the region. Hezbollah attacked with rockets and guerrilla warfare tactics. Over 1,000 people in Lebanon lost their lives in the weeks of conflict between Hezbollah and Israeli Defense Force, and about a million Lebanese civilians were displaced from their homes because of the conflict. The death toll for Israelis numbers less than 200.
