From the root H1696 (to speak), dabar is a common and significant Hebrew word. It encompasses a wide range of meanings, including a spoken word, a matter or affair, a thing, a command, or a promise. It refers not just to the utterance itself, but to the reality and substance behind it.
The "word of the LORD" (dabar-YHWH) is a recurring and powerful theme, representing God's active and powerful self-revelation in the world. God's dabar is creative (Genesis 1, Psalm 33:6), authoritative, and always accomplishes its purpose (Isaiah 55:11). The Ten Commandments are referred to as the "Ten Words" (aseret ha-debarim). This concept of a dynamic, powerful, and personal word from God provides the theological foundation for the New Testament understanding of Jesus as the incarnate Logos (Word) of God (John 1:1).
