“Likewise ye husbands, dwel with them according to knowledge, giuing honour vnto the wife as vnto the weaker vessel, and as being heires together of the grace of life, that your prayers be not hindered.”
1611 King James Version (KJV)
3:7 Dwell with the woman according to knowledge - Knowing they are weak, and therefore to be used with all tenderness. Yet do not despise them for this, but give them honour - Both in heart, in word, and in action; as those who are called to be joint - heirs of that eternal life which ye and they hope to receive by the free grace of God. That your prayers be not hindered - On the one part or the other. All sin hinders prayer; particularly anger. Anything at which we are angry is never more apt to come into our mind than when we are at prayer; and those who do not forgive will find no forgiveness from God.
1Pe 3:7 Ye husbands. Duties of Christian husbands are now briefly stated. They are to dwell with [them]. The fact that their wives are unconverted is no ground for separation, but if the wife is converted, still stronger is the bond. According to knowledge. A knowledge that shows judgment, moderation and gentleness as toward one weaker than himself. As being heirs together of the grace of life. "Joint-heirs" (Revised Version). Hence "one in Christ Jesus". The home life is to be regulated according to knowledge. That your prayers be not hindered. Mutual prayer is not possible unless there is mutual love and forbearance. Nor can the husband's prayers be acceptable unless he treats his wife aright.
