A decree, statute, or inscription — something engraved or inscribed permanently. From the root chaqaq (to engrave, decree). Represents authority expressed through permanent, authoritative writing.
The concept of engraving (decreeing) connects law with permanence. God's commandments were 'engraved' on stone tablets (Ex 32:16). His laws are to be 'written on the heart' (Jer 31:33). When rulers issue cheqeq, they exercise God-delegated authority. The 'Lawgiver' (mechoqeq) in Genesis 49:10 is a Messianic title — the one who has ultimate authority to decree and inscribe God's will for humanity.
