Exodus 4:6-9 (ANIV)
6 Then the Lord said, “Put your hand inside your cloak.” So Moses put his hand into his cloak, and when he took it out, it was leprous,  like snow.
7 “Now put it back into your cloak,” he said. So Moses put his hand back into his cloak, and when he took it out, it was restored, like the rest of his flesh.
8 Then the Lord said, “If they do not believe you or pay attention to the first miraculous sign, they may believe the second. 9 But if they do not believe these two signs or listen to you, take some water from the Nile and pour it on the dry ground. The water you take from the river will become blood on the ground.”
The Hebrew word used for various diseases affecting the skin, not necessarily leprosy.
TIME OF DAY:
Diffused sunlight from above illuminates this scene.
This is a simple scene, focussing entirely on Moses’ reaction to his hand becoming leprous. I have used radiating rays of pale yellow and white colour to focus the viewers attention on Moses hand, which has white speckles of leprosy on it.
