Leviticus 2:13

And every gift of your sacrifice shall be seasoned with salt; omit not the salt of the covenant of the Lord from your sacrifices: on every gift of yours ye shall offer salt to the Lord your God.

And every oblation of thy meat offering shalt thou season with salt; neither shalt thou suffer the salt of the covenant of thy God to be lacking from thy meat offering: with all thine offerings thou shalt offer salt.

Every offering of your meal offering you shall season with salt. You shall not allow the salt of the covenant of your God to be lacking from your meal offering. With all your offerings you shall offer salt.
