Exodus 21:6

21:6 then his master must bring him to the judges, ¹  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. ² 

Deuteronomy 15:17

15:17 you shall take an awl and pierce a hole through his ear to the door. ³  Then he will become your servant permanently (this applies to your female servant as well).

[21:6]  ¹ 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.

[21:6]  ² tn Or “till his life’s end” (as in the idiom: “serve him for good”).

[15:17]  ³ sn When the bondslave’s ear was drilled through to the door, the door in question was that of the master’s house. In effect, the bondslave is declaring his undying and lifelong loyalty to his creditor. The scar (or even hole) in the earlobe would testify to the community that the slave had surrendered independence and personal rights. This may be what Paul had in mind when he said “I bear on my body the marks of Jesus” (Gal 6:17).
