The Bible does not explicitly state that Ham married his daughter.
Here's what the Bible says about Ham and his family:
* Ham's Lineage: Ham was one of the three sons of Noah (Genesis 6:10). His brothers were Shem and Japheth. After the great flood, the sons of Noah were the ancestors of all the people of the earth.
* Ham's Sons: Ham had four sons: Cush, Mizraim, Put, and Canaan (Genesis 10:6). These sons were the founders of various nations.
* The Incident with Noah: The key incident involving Ham is found in Genesis 9:20-27. After the flood, Noah planted a vineyard, drank some of the wine, and became drunk. He lay uncovered in his tent. Ham saw his father's nakedness and told his two brothers, Shem and Japheth, about it. Shem and Japheth, out of respect, covered their father without looking at him. When Noah awoke and learned what Ham had done, he cursed Ham's son, Canaan, to be a servant to his brothers.
Why the Question Arises:
The incident in Genesis 9:20-27 is sometimes interpreted in various ways, leading to different interpretations, including speculations about the nature of Ham's "sin." Some interpretations suggest that Ham's actions were more than simply seeing his father naked, leading to questions about possible incestuous acts or other serious offenses. However, the text does not explicitly state these things.
Conclusion:
The Bible does not explicitly say that Ham married his daughter. The Genesis passage describes Ham seeing his father naked and the subsequent curse on Canaan. Interpretations of this passage vary, but the Bible itself provides no direct evidence of incestuous behavior.
