The Hebrew noun emer denotes speech, a word, or an utterance, derived from the verb amar (H559, 'to say'). It appears about 48 times in the Old Testament, often in poetic and wisdom literature to emphasize the power and authority of what is spoken.
In Hebrew thought, the spoken word was not merely sound — it carried the power of the speaker. Emer is used especially for the authoritative word of God. Psalm 19 celebrates God's speech: "The precepts of the LORD are right, giving joy to the heart. The commands of the LORD are radiant, giving light to the eyes." Job uses emer to describe his earnest wrestling with God's words (Job 6:10; 22:22). The synonym imrah (H565) is also common in poetic parallelism. Together they form part of the rich Hebrew vocabulary for divine communication — reminding Israel that God is not silent. He speaks, and His words accomplish everything He intends (Isaiah 55:11). The theology of divine speech runs from creation (God said...) through prophecy and culminates in the Incarnation: the eternal Word becoming flesh (John 1:14).
