'Separation' in the Bible

And I will put a separation between my people and thy people; to-morrow shall this sign be.

the ark, and its staves; the mercy-seat, and the veil of separation;

and the covering of rams' skins dyed red, and the covering of badgers' skins, and the veil of separation;

And he brought the ark into the tabernacle, and hung up the veil of separation, and covered the ark of the testimony; as Jehovah had commanded Moses.
