Leviticus 2:13

Salt. In every sacrifice salt was to be used, which is an emblem of wisdom and discretion, without which none of our performances are agreeable to God. (Challoner) --- Salt is not prescribed in the sacrifices of animals. But it was to be used in them, as we learn from the Jews, and from St. Mark ix. 48, Every victim shall be salted. The ancient poets never specify salt in their descriptions of sacrifices. But Pliny assures us, that in his time it was of the greatest authority, and always used in sacrifice, with cakes. Maxime in sacris intelligebatur salis auctoritas, quando nulla conficiuntur sine mola salsa. (B. xxxi. 7.) --- Covenant. It is so called, because it was a symbol of the durable condition of the alliance with God, which was renewed in every sacrifice; (Calmet) or it may signify "the salt prescribed" by God: for the law and covenant are often used synonymously. (Menochius) --- Let your speech be always in grace, seasoned with salt, Colossians iv. 6. See Numbers xviii. 19.
