The ear, the thumb, and the toe:
Lev 14: 17 And of the rest of the oil in his hand, the priest shall put some on the tip of the right ear of him who is to be cleansed, on the thumb of his right hand, and on the big toe of his right foot, on the blood of the trespass offering.
When the oil of Holy Spirit comes upon a believer, He clarifies our hearing, our works, and our walk as our steps become ordered of the Lord.
Father, send Holy Spirit to us today. Holy Spirit, cause us to hear clear, work effectively, and walk carefully, following Jesus, Amen”
