28 And the Lord spake unto Moses, saying,
29 Speak unto the children of Israel, saying, He that offereth the sacrifice of his peace offerings unto the Lord shall bring his oblation unto the Lord of the sacrifice of his peace offerings.
30 His own hands shall bring the offerings of the Lord made by fire, the fat with the breast, it shall he bring, that the breast may be waved for a wave offering before the Lord.
31 And the priest shall burn the fat upon the altar: but the breast shall be Aaron’s and his sons’.
32 And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings.
33 He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for his part.
34 For the wave breast and the heave shoulder have I taken of the children of Israel from off the sacrifices of their peace offerings, and have given them unto Aaron the priest and unto his sons by a statute for ever from among the children of Israel.
When the Lord says that He has “taken of the children of Israel” the “wave breast and the heave shoulder,” and “given them unto Aaron the priest and unto his sons,” it seems to suggest that he has taken their heart (breast) and their strength (shoulder) and assigned them to the tabernacle. That is where the people’s devotion and effort should be directed. Of course, they would have their own personal love and work in life, but even loving a child can be part of loving the ritual, and part of working for one’s livelihood can be part of working for the holy place. All of it could be directed through the personal towards the root covenant.
Of course, the priests and the tabernacle were not one and the same as God, but directing one’s devotion to them would be like having a signpost to follow, which would lead one to the actual destination. It would be like following a star, though the real target is the Messiah who lives beneath it. By giving their hearts and strength to the representatives that God had made accessible to them, the ancient Israelites would also be moving their spirits towards the unseen Father.
