LXX Num 18:19

πᾶν ἀφαίρεμα τῶν ἁγίων, ὅσα ἀν’ ἀφέλωσιν οἱ υἱοὶ Ἰσραὴλ Κυρίῳ, σοὶ δέδωκα καὶ τοῖς υἱοῖς σου καὶ ταῖς θυγατράσιν σου μετὰ σοῦ, νόμιμον αἰώνιον· διαθήκη ἁλὸς αἰωνίου ἐστὶν ἔναντι Τυρίου σοὶ καὶ τῷ σπέρματί σου μετὰ σέ.

All the holy offerings that the Israelites present to the LORD I give to you and to your sons and daughters as a permanent statute. It is a permanent covenant of salt before the LORD for you and your offspring.”
