According to the New Testament's account of the Flood, eight people entered Noah's Ark.
First Peter 3:20 refers to “eight souls” being brought safely through the water. The eight are understood from Genesis as Noah, Noah's wife, Noah's three sons, and the three wives of those sons. Genesis 7:13 names Noah, his sons Shem, Ham, and Japheth, and the women entering the ark.
The figure is sometimes confused with the number of animals aboard, which Genesis describes in separate terms. It is also easy to count only Noah and his sons while overlooking the four women. The eight-person total includes Noah's wife and the wives of his three sons.
This answer is specifically supported by the New Testament wording in 1 Peter, while the corresponding family list comes from Genesis. Together, the passages establish the conventional biblical count of eight human passengers.
