You shall season all your cereal offerings with salt; you shall not let the salt of the covenant with your God be lacking from your cereal offering; with all your offerings you shall offer salt.
All the holy offerings which the people of Israel present to the Lord I give to you, and to your sons and daughters with you, as a perpetual due; it is a covenant of salt for ever before the Lord for you and for your offspring with you.”
“You are the salt of the earth; but if salt has lost its taste, how shall its saltness be restored? It is no longer good for anything except to be thrown out and trodden under foot by men.
