Leviticus 14:14 Then the priest will take some of the blood from the guilt (trespass) offering and put it on the right ear lobe, on the right thumb, and on the big toe of the right foot of the one to be cleansed.
14:17 The priest will put some of the oil that is still in his hand on the right ear lobe, on the right thumb, and on the big toe of the right foot of the one to be cleansed. These are the same places he had put the blood of the guilt offering.
Why put the blood where He said? Why an ear lobe, why a thumb, why a big toe? God knows what these things did and what they represent. The ear lobe is designed to hear higher sounding things from the front only. It servers a purpose, God designed it for a purpose and I figure that this sprinkling of blood on it means some thing.
The right thumb because that separates us from all other things on this planet. It is what we use to make things. The Right big toe function is to help us balance, and to propel us forward during walking or running. This signifies our walk with God and our balance that must be sustained during this walk. If we trip in our walk with God we need help from Christ and sin is what trips us up. The lepers are a form of sin in our lives. We need a cleansing of the flesh.
The 3 mean you can’t hear the higher things right, you can’t make it right, and you can’t walk right. That is why the leper needed to have the blood sprinkled in those areas. It signified that he was healed but need the blood applied to those areas because it was the cause of his sin. Sin will be found in the way we are hearing, doing, or walking. He not only signifies that He cleansed it but now was with oil sanctifying it.
LOCALIZATION
We are also able to perceive the direction of a sound source with some accuracy. Left and right location is determined by perception of the difference of arrival time or difference in phase of sounds at each ear. If there are more than two arrivals, as in a reverberant environment, we choose the direction of the first sound to arrive, even if later ones are louder. Localization is most accurate with high frequency sounds with sharp attacks.
Height information is provided by the shape of our ears. If a sound of fairly high frequency arrives from the front, a small amount of energy is reflected from the back edge of the ear lobe. This reflection is out of phase for one specific frequency, so a notch is produced in the spectrum. The elongated shape of the lobe causes the notch frequency to vary with the vertical angle of incidence, and we can interpret that effect as height. Height detection is not good for sounds originating to the side or back, or lacking high frequency content.
