Numbers 18:19

19. A covenant of salt Salt symbolizes the unbending truthfulness of that self-surrender to the Lord implied in the sacrifice, excluding all impurity and hypocrisy.

“Unsavoury all our offerings are

Till acceptable through thy Son:

But hear well pleased our praise and prayer

Presented in his Name alone.

The salt we borrow from our Lord,

His meritorious righteousness,

And every deed, and thought, and word

Is season’d now with Jesus’ grace.” C. Wesley.

In common life salt was the emblem of a covenant. Among the modern Arabs, the parties to a treaty ratify it by eating bread and salt together. See Leviticus 2:13; Mark 9:49; Luke 14:34, notes.

For ever See Leviticus 3:17, note.
