In like manner, wives, be in subjection to your own husbands; so that, even if any don't obey the Word, they may be won by the behavior of their wives without a word;

 This word introduces us to a special way of looking at the Old Testament. There are two closely connected words. There is tupos ( G5179) , type, which means a seal, and there is antitupos ( G499) , antitype, which means the impression of the seal. Clearly, between the seal and its impression there is the closest possible correspondence. So there are people and events and customs in the Old Testament which are types, and which find their antitypes in the New Testament. The Old Testament event or person is like the seal; the New Testament event or person is like the impression; the two answer to each other. We might put it that the Old Testament event symbolically represents and foreshadows the New Testament event. The science of finding types and antitypes in the Old and the New Testaments is very highly developed. But to take very simple and obvious examples, the Passover Lamb and the scapegoat, who bore the sins of the people, are types of Jesus; and the work of the High Priest in making sacrifice for the sins of the people is a type of his saving work. Here Peter sees the bringing safely through the waters of Noah and his family as a type of baptism.
