Who was Noah's youngest son?
The name of Noah’s youngest son is given to us in scripture. In the genealogies, the Bible consistently lists the male children in the order of their birth. In Genesis 5:32 we find the order of birth for Noah’s children to be as follows:
And Noah was five hundred years old, and Noah became the father of Shem, Ham, and Japheth. (NASB) Genesis 5:32
Therefore, it seems reasonable to conclude that Japheth was the youngest child. Genesis 9:2 gives us his sons.
The sons of Japheth were Gomer and Magog and Madai and Javan and Tubal and Meshech and Tiras. (NASB) Genesis 9:2
It is wonderful that God has given us the genealogies. It was a way of understanding history and eventually the right of Jesus Christ to sit on the throne of King David. Praise the Lord!
