הֲלֹ֤א לָכֶם֙ לָדַ֔עַת כִּ֞י יְהוָ֣ה ׀ אֱלֹהֵ֣י יִשְׂרָאֵ֗ל נָתַ֨ן מַמְלָכָ֧ה לְדָוִ֛יד עַל־יִשְׂרָאֵ֖ל לְעוֹלָ֑ם ל֥וֹ וּלְבָנָ֖יו בְּרִ֥ית מֶֽלַח׃ (ס)
ought ye not to know that the LORD, the God of Israel, gave the kingdom over Israel to David for ever, even to him and to his sons by a covenant of salt?
Leviticus
You shall salt all your meal-offerings with salt and you shall not omit salt, the covenant of your God from [being placed] upon your meal-offerings. You shall bring salt on every one of your offerings.
Numbers
All of the sacred terumah-gifts that Bnei Yisroel offer to Adonoy, I have given to you, your sons and daughters with you as an everlasting portion; an eternal covenant of salt before Adonoy to you and your children that are with you.”
