The Hebrew word katab means to engrave or inscribe. In Exodus 31:18 God engraved the Ten Commandments onto stone tablets with His own finger. He created permanent records of His Words lest people forget what He said. Even after Moses broke the first set, God had Moses make new tablets so He could rewrite the same commandments. (Exod. 34:1). God values His words—so much that He wants them written on human hearts. (Prov. 7:1-3).
