An interpretation of Exodus 17:15, depicting Moses as a South Asian man with a weathered face, deep-set eyes and a long white beard. He is building an altar out of stones, showing evidence of labor and reverence in his action. The landscape around him is vast and desolate, possibly a desert, reflecting the biblical times. On top of the altar, an ancient script almost glows, representing the name 'Jehovah-nissi'. Capture this scene in a style reminiscent of 16th century renaissance painting with emphasis on detail, realism, and the use of light and shadow.
