“But Christ came as High Priest of the good things to come, with the greater and more perfect tabernacle not made with hands, that is, not of this creation. Not with the blood of goats and calves , but with His own blood He entered the Most Holy Place, once for all, having obtained eternal redemption.” Hebrews 9: 11-12
During your lessons on Moses, please give yourself time to study the tabernacle. Hebrews 8:5 tells us that the earthly tabernacle was a “copy and shadow of the heavenly things”. God is very specific when He refers to the tabernacle or His temple. Men could never presume to come before the LORD unless he came in the prescribed manner. Make sure you go over words like “mercy” so the kids have a good understanding of this characteristic.
Note: “the Most Holy Place” is used in many translations, including KJV. “Holy of Holies” is used in American Standard version, and a few others.
