Leviticus 16:3 Thus shall Aaron come into the holy place: with a young bullock for a sin offering, and a ram for a burnt offering. 4 He shall put on the holy linen coat, and he shall have the linen breeches upon his flesh, and shall be girded with a linen girdle, and with the linen mitre shall he be attired: these are holy garments; therefore shall he wash his flesh in water, and so put them on.
[Patriarchs & Prophets pp 353>354] Before entering into the presence of God through the ministration of the priest, they were to engage in earnest searching of heart and confession of sin. They united in silent prayer, with their faces toward the holy place. Thus their petitions ascended with the cloud of incense, while faith laid hold upon the merits of the promised Savior prefigured by the atoning sacrifice. The hours appointed for the morning and the evening sacrifice were regarded as sacred, and they came to be observed as the set time for worship throughout the Jewish nation. And when in later times the Jews were scattered as captives in distant lands, they still at the appointed hour turned their faces toward Jerusalem and offered up their petitions to the God of Israel.
In this custom Christians have an example for morning and evening prayer. While God condemns a mere round of ceremonies, without the spirit of worship, He looks with great pleasure upon those who love Him, bowing morning and evening to seek pardon for sins committed and to present their requests for needed blessings. The show-bread was kept ever before the Lord as a perpetual offering. Thus it was a part of the daily sacrifice. It was called show-bread, or “bread of the presence,” because it was ever before the face of the Lord. It was an acknowledgment of man's dependence upon God for both temporal and spiritual food, and that it is received only through the mediation of Christ.
God had fed Israel in the wilderness with bread from heaven, and they were still dependent upon His bounty, both for temporal food and spiritual blessings. Both the manna and the show-bread pointed to Christ, the living Bread, who is ever in the presence of God for us. He Himself said, “I am the living Bread which came down from heaven.” John 6:48-51.
John 6:33 For the bread of God is he which cometh down from heaven, and giveth life unto the world. 34 Then said they unto him, Lord, evermore give us this bread. 35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
May God add His blessing to the study of His word. "Good night" and God bless!
