'Separation' in the Bible

'And against all the sons of Israel a dog sharpeneth not its tongue, from man even unto beast, so that ye know that Jehovah doth make a separation between the Egyptians and Israel;

'And thou hast put the vail under the hooks, and hast brought in thither within the vail the ark of the testimony; and the vail hath made a separation for you between the holy and the holy of holies.
