Cleansing From Infectious Skin Diseases
1 The LORD said to Moses, 2 "These are the regulations for the diseased person at the time of his ceremonial cleansing, when he is brought to the priest: 3 The priest is to go outside the camp and examine him. If the person has been healed of his infectious skin disease, [a] 4 the priest shall order that two live clean birds and some cedar wood, scarlet yarn and hyssop be brought for the one to be cleansed. 5 Then the priest shall order that one of the birds be killed over fresh water in a clay pot. 6 He is then to take the live bird and dip it, together with the cedar wood, the scarlet yarn and the hyssop, into the blood of the bird that was killed over the fresh water. 7 Seven times he shall sprinkle the one to be cleansed of the infectious disease and pronounce him clean. Then he is to release the live bird in the open fields.
The Lord was showing me that there was salvation even before the Lord Jesus came to save us. This was done in ritual sacrifice. The dead bird represents the sacrifice of Jesus and we live again as free creatures. The fact that the priest is ordered to put the dead bird, scarlet yarn, and cedar says that this is a representation of Jesus on the cross.
