Final answer:
The showbread, or Bread of the Presence, was an offering in ancient Israelite culture, symbolizing the twelve tribes of Israel and consumed by priests in the sanctuary on a weekly basis.
Step-by-step explanation:
The showbread, also known as the shewbread or the Bread of the Presence, was a religious offering in ancient Israelite culture described in the Bible. This bread was placed on a special table in the sanctuary of the Tabernacle, and later in the Temple in Jerusalem. The showbread consisted of twelve loaves which represented the twelve tribes of Israel and was set before the Lord as a perpetual offering. Every Sabbath, new loaves replaced the old, and the priests would consume the bread that had been in the presence of the Lord for that week.
