And He said, “If you diligently obey the voice of יהוה your Elohim and do what is right in His eyes, and shall listen to His commands and shall guard all His laws, I shall bring on you none of the diseases I brought on the Mitsrites, for I am יהוה who heals you.”
“When a man has on the skin of his body a swelling, a scab, or a bright spot, and it shall become on the skin of his body like a leprous infection, then he shall be brought to Aharon the priest or to one of his sons the priests.
“However, if the priest indeed comes in and looks at it and sees that the plague has not spread in the house after the house was plastered, then the priest shall pronounce the house clean, because the plague is healed.
