"Live in temporary shelters for seven days: All native-born Israelites are to live in such shelters so your descendants will know that I had the Israelites live in temporary shelters when I brought them out of Egypt. I am the LORD your God." (Leviticus 23:42-43)
In this photo from 1950, a family of olim (immigrants) build the traditional temporary shelter known as a sukkah in order to celebrate their first Sukkot (the biblical Feast of Tabernacles) in the Holy Land. Shabbat shalom and have a festive Sukkot.
