Elijah “walked forty days and forty nights as far as the mountain of God at Horeb. There he went into a cave, and there he spent the night.
Then the word of the Lord came to him. He said to him, ‘Why are you here, Elijah?”
Elijah answers, and the word of the Lord calls “Come out,” …”and stand on the mountain before the Lord”.
The Lord passed by, and his power is revealed in a great destructive wind, an earthquake and fire, but the Lord is not in them, and then a soft murmuring sound (fn. “a still, small voice.”).
Elijah heard this, wrapped his mantle about his face and went out and stood at the entrance of the cave where a voice addressed him (which is the Lord): “Why are you here, Elijah?”
Elijah answers and the Lord instructs him to go to Damascus and anoint Hazael as King of Aram, Jehu as King of Israel, and Elisha as the prophet to succeed him. 1 Kings 19/8-16 Tanakh JPS 1985 (edited).
26And God said, “Let us make man in our image, after our likeness. They shall rule the fish of the sea, the birds of the sky, the cattle, the whole earth, and all the creeping things that creep on earth.” 27And God created man in His image, in the image of God He created him; male and female He created them. Genesis 1/26-27 Tanakh JPS 1985.
The “word of the Lord” came to and is with Elijah at the front of the cave and says “Why are you here, Elijah?” and “come out” and “stand on the Mountain before the Lord”.
The Lord passed by, his power is revealed (earth, wind and fire) without his presence (He is not in them), and the Lord says “Why are you here, Elijah?”
The “word of the Lord” is at the cave with Elijah and speaks the same words as G-d speaks to Elijah away from the cave after He passed by and revealed His power at the cave (but He was not at the cave).
The soft murmuring sound (fn. “a still, small voice.”) would be the same words from G-d that the “word of the Lord” had spoken based on the same question having been asked twice before (Why are you here, Elijah?) which was come out and stand on the Mountain before the Lord. And for the reason that is what Elijah did after hearing the still, small voice. Elijah ignored the “word of the Lord” and was unmoved by G-d’s power. But a whisper from G-d Himself had the desired result of Elijah going to the front of the cave.
Elijah gives the same answer to the “word of the Lord” as he gives to the Lord: “I am moved by zeal for the Lord, the God of Hosts, for the Israelites have forsaken your covenant, torn down Your alters, and put Your prophets to the sword. I alone am left, and they are out to take my life”.
The spirit of God and God have the same image and the same likeness in the unseen realm of God, and this image and likeness is in man (persons of spirit with emotions and feelings).
God speaks to the spirit of God as one person to another person in chapter one of the book of Genesis. God speaks to man as one person to another person. The spirit of God speaks the words of the Lord to man as one person to another person and is the “word of the Lord” throughout the Tanakh.
The spirit of the Holy G-d is like an angelic messenger of the Lord’s words. G-d is in him and can speak through him just as G-d speaks through the angel of the Lord in the burning bush to Moses.
