Discovery BoxExodus 29:20 
Context29:20 and you are to kill the ram and take some of its blood and put it on the tip of the right ear of Aaron, on the tip of the right ear of his sons, on the thumb of their right hand, and on the big toe of their right foot, 1 and then splash the blood all around on the altar.
Exodus 21:6
Context21:6 then his master must bring him to the judges, 2 and he will bring him to the door or the doorposts, and his master will pierce his ear with an awl, and he shall serve him forever. 3
1 sn By this ritual the priests were set apart completely to the service of God. The ear represented the organ of hearing (as in “ears you have dug” in Ps 40 or “awakens my ear” in Isa 50), and this had to be set apart to God so that they could hear the Word of God. The thumb and the hand represented the instrument to be used for all ministry, and so everything that they “put their hand to” had to be dedicated to God and appropriate for his service. The toe set the foot apart to God, meaning that the walk of the priest had to be consecrated – where he went, how he conducted himself, what life he lived, all belonged to God now.
2 tn The word is הָאֱלֹהִים (ha’elohim). S. R. Driver (Exodus, 211) says the phrase means “to God,” namely the nearest sanctuary in order that the oath and the ritual might be made solemn, although he does say that it would be done by human judges. That the reference is to Yahweh God is the view also of F. C. Fensham, “New Light on Exodus 21:7 and 22:7 from the Laws of Eshnunna,” JBL 78 (1959): 160-61. Cf. also ASV, NAB, NASB, NCV, NRSV, NLT. Others have made a stronger case that it refers to judges who acted on behalf of God; see C. Gordon, “אלהים in its Reputed Meaning of Rulers, Judges,” JBL 54 (1935): 134-44; and A. E. Draffkorn, “Ilani/Elohim,” JBL 76 (1957): 216-24; cf. KJV, NIV.
3 tn Or “till his life’s end” (as in the idiom: “serve him for good”).
