1 Kings 8:1-11
The entrance of the ark 8:1-11
The Israelites regarded the ark as the throne of Yahweh. It was the place where He manifested His presence in a localized way and where He received the blood that atoned for the Israelites' sins on the Day of Atonement. The ark had rested in David's tabernacle in Zion since David had brought it from the house of Obed-edom (2Sa_6:17). It was the only item in the temple that was not new. Perhaps God did not change it to help the people realize that He, symbolized by the ark, had not changed. His person and methods of dealing with them at the mercy seat were the same as they had been.
The ceremony of installing the ark in Solomon's temple took place during the Feast of Tabernacles. This was one of the feasts that the Mosaic Law specified that all Israelite males had to attend (Lev_23:33-36). This feast was a commemoration of the Lord's faithfulness during His people's wilderness wanderings. It looked back to their slavery in Egypt and forward to their establishment in the Promised Land. The bringing of the ark into the temple symbolized the fulfillment of that hope. Evidently Solomon waited for this feast in order to celebrate the dedication of the temple, and used the months following the completion of construction to furnish it and to prepare for the celebration.
