Pillars are used as imagery to describe the earth’s foundation. When it quakes, Elohim holds the pillars firm for all the people on the earth (Psalm 75:4). The first reference to a pillar is in Genesis 35:14 when Ya’akov (Jacob) sets up a standing stone or pillar at Beit-el. While the Israelites wandered through the wilderness, the glory of Adonai led them by a pillar of cloud by day and a pillar of fire by night. His pillar shaded them from the heat of the day and kept them warm at night. His pillar protected them from their enemies and moved with them for 40 years. His pillar lived above the Ark of the Covenant in the Tabernacle; His pillar was their sukkah of covering for 40 years.
