The Temple was up on a rock, Mount Moriah, and He would be hidden in His secret place. Normally you think of the secret place as the Holy of Holies or the Holy Place.
Hidden is the Greek word krupto. Some of you may own some cryptocurrency. It is Strong's number 2928, and it means concealed in a safe place, secreted. We saw this in Psalm 27:5, In the secret place of His tabernacle He shall hide me. So we are safe.
