In the Old Testament, God commanded that all grain offerings be salted. Salt signifies that God’s covenant does not change. (Lev 2:13, Num 18:19)

Lev 2:13 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.

Num 18:19 All the heave offerings of the holy things, which the children of Israel offer unto the Lord, have I given thee, and thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the Lord unto thee and to thy seed with thee.

God gave the kingdom of Israel to David and his descendants through a covenant of salt. (2 Chronicles 13:5)

God has promised to bless us, and he has sworn to himself that he will keep that promise. (Gen 15:9, 17)

Gen 15:9 And he said unto him, Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon.
17 And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.

In the Old Testament, God promised to send us Christ to bless us and to destroy our enemies through him. (Gen 22:17-18)

Gen 22:17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;
18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.

The descendant of Abraham that God promised to send to bless us is Jesus Christ. (Gal 3:16)

Gal 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
