I am looking a vintage hand drawn style that somehow incorporates an image of Mt. Horeb. Whisper gets its name from the story in the bible found in 1 Kings 19. It says.... "There he came to a cave and lodged in it. And behold, the word of the Lord came to him, and he said to him, “What are you doing here, Elijah?” 10 He said, “I have been very jealous for the Lord, the God of hosts. For the people of Israel have forsaken your covenant, thrown down your altars, and killed your prophets with the sword, and I, even I only, am left, and they seek my life, to take it away.” 11 And he said, “Go out and stand on the mount before the Lord.” And behold, the Lord passed by, and a great and strong wind tore the mountains and broke in pieces the rocks before the Lord, but the Lord was not in the wind. And after the wind an earthquake, but the Lord was not in the earthquake. 12 And after the earthquake a fire, but the Lord was not in the fire. And after the fire the sound of a low whisper.[a] 13 And when Elijah heard it, he wrapped his face in his cloak and went out and stood at the entrance of the cave. And behold, there came a voice to him and said, “What are you doing here, Elijah?”"
Supposedly this story took place on Mt. Horeb. I have attached some images of this mountain.
