Keluaran 25:30

25:30 You are to set the Bread of the Presence ¹  on the table before me continually.

[25:30]  ¹ sn The name basically means that the bread is to be set out in the presence of Yahweh. The custom of presenting bread on a table as a thank offering is common in other cultures as well. The bread here would be placed on the table as a symbol of the divine provision for the twelve tribes – continually, because they were to express their thanksgiving continually. Priests could eat the bread after certain times. Fresh bread would be put there regularly.
