2 Chronicles 13:5

A covenant of salt] cp. Numbers 18:19. The use of salt in connexion with sacrifice (see Leviticus 2:13) probably arose from its association with a meal; and 'there is salt between us' is said to be a phrase still employed to denote the bond which secures, for any one who has partaken of an Arab's hospitality, protection and (in case of need) assistance.
