7 Likewise, you husbands should live with your wives in understanding, showing honor to the weaker female sex, since we are joint heirs of the gift of life, so that your prayers may not be hindered. 2
17 For it is better to suffer for doing good, if that be the will of God, than for doing evil.
18 For Christ also suffered 5 for sins once, the righteous for the sake of the unrighteous, that he might lead you to God. Put to death in the flesh, he was brought to life in the spirit.
19 In it he also went to preach to the spirits in prison, 6
21 This prefigured baptism, which saves you now. It is not a removal of dirt from the body but an appeal to God 7 for a clear conscience, through the resurrection of Jesus Christ,
1 [1-6] The typical marital virtues of women of the ancient world, obedience, reverence, and chastity (1 Peter 3:1-2), are outlined here by the author, who gives them an entirely new motivation: Christian wives are to be virtuous so that they may be instrumental in the conversion of their husbands. In imitation of holy women in the past (1 Peter 3:5) they are to cultivate the interior life (1 Peter 3:4) instead of excessive concern with their appearance (1 Peter 3:3).
2  Husbands who do not respect their wives will have as little success in prayer as those who, according to Paul, have no love: their prayers will be ＂a resounding gong or a clashing cymbal＂ (1 Cor 13:1). Consideration for others is shown as a prerequisite for effective prayer also in Matthew 5:23-24; 1 Cor 11:20-22; James 4:3. After all, whatever the social position of women in the world and in the family, they are equal recipients of the gift of God's salvation. Paul is very clear on this point, too (see 1 Cor 11:11-12; Gal 3:28).
3 [8-12] For the proper ordering of Christian life in its various aspects as described in 1 Peter 2:11-3:9, there is promised the blessing expressed in Psalm 34:13-17. In the Old Testament this refers to longevity and prosperity; here, it also refers to eternal life.
4 [13-22] This exposition, centering on 1 Peter 3:17, runs as follows: by his suffering and death Christ the righteous one saved the unrighteous (1 Peter 3:18); by his resurrection he received new life in the spirit, which he communicates to believers through the baptismal bath that cleanses their consciences from sin. As Noah's family was saved through water, so Christians are saved through the waters of baptism (1 Peter 3:19-22). Hence they need not share the fear of sinners; they should rather rejoice in suffering because of their hope in Christ. Thus their innocence disappoints their accusers (1 Peter 3:13-16; cf Matthew 10:28; Romans 8:35-39).
5  Suffered: very many ancient manuscripts and versions read ＂died.＂ Put to death in the flesh: affirms that Jesus truly died as a human being. Brought to life in the spirit: that is, in the new and transformed existence freed from the limitations and weaknesses of natural human life (cf 1 Cor 15:45).
6  The spirits in prison: it is not clear just who these spirits are. They may be the spirits of the sinners who died in the flood, or angelic powers, hostile to God, who have been overcome by Christ (cf 1 Peter 3:22; Genesis 6:4; Enoch 6-36, especially 1 Peter 3:21:6; 2 Enoch 7:1-5).
7  Appeal to God: this could also be translated ＂pledge,＂ that is, a promise on the part of Christians to live with a good conscience before God, or a pledge from God of forgiveness and therefore a good conscience for us.
