According to 1 Peter, eight human beings were saved inside Noah’s Ark.
First Peter 3:20 refers to “eight souls” being brought safely through the water. The eight are Noah, his wife, their three sons, and the three sons’ wives. This total is also consistent with the family group listed in Genesis, although Genesis does not present the number as a standalone headline.
The figure is easy to confuse with other numbers in the Flood traditions. The ark carried animals in varying quantities depending on the passage and translation, while the human survivors are counted as eight in the New Testament reference. The number twelve, common in other biblical stories, does not apply here.
The verse uses the Flood as part of a theological argument about salvation and water. Its numerical statement is nevertheless clear: the surviving human group associated with Noah’s ark consisted of eight people.
