1 Corinthians 7:3

7:3 A husband should give to his wife her sexual rights, ¹  and likewise a wife to her husband.

1 Corinthians 11:6

11:6 For if a woman will not cover her head, she should cut off her hair. But if it is disgraceful for a woman to have her hair cut off or her head shaved, she should cover her head.

1 Corinthians 11:15

11:15 but if a woman has long hair, it is her glory? For her hair is given to her for a covering. ² 

[7:3]  ¹ tn Grk “fulfill the obligation” or “pay the debt,” referring to the fulfillment of sexual needs within marriage.

[11:15]  ² sn No word for veil or head covering occurs in vv. 3-14 (see the note on authority in v. 10). That the hair is regarded by Paul as a covering in v. 15 is not necessarily an argument that the hair is the same as the head covering that he is describing in the earlier verses (esp. v. 10). Throughout this unit of material, Paul points out the similarities of long hair with a head covering. But his doing so seems to suggest that the two are not to be identified with each other. Precisely because they are similar they do not appear to be identical (cf. vv. 5, 6, 7, 10, 13). If head covering = long hair, then what does v. 6 mean (“For if a woman will not cover her head, she should cut off her hair”)? This suggests that the covering is not the same as the hair itself.
