And every offering of your grain offering shall you season with salt; neither shall you allow the salt of the covenant of your God to be lacking from your grain offering: with all your offerings you shall offer salt.
All the heave offerings of the holy things, which the children of Israel offer unto the LORD, have I given you, and your sons and your daughters with you, by a statute forever: it is a covenant of salt forever before the LORD unto you and to your descendants with you.
You are the salt of the earth: but if the salt has lost its savor, how shall it be salted? it is thereafter good for nothing, but to be cast out, and to be trodden under foot of men.
