If we look at the Scripture passage we read today, we could see that there were ancestors of faith who knew the end of the first world. They were none other than Methuselah, Lamech, and Noah. Methuselah was Noah’s grandfather, and Lamech was his father. Methuselah had Lamech at the age of 187, and Lamech had Noah at the age of 182. So, Methuselah was 369 when Noah was born. Noah’s grandfather, Methuselah lived for 969 years, and his father Lamech lived for 777 years. When Noah was 500, he had Shem, Ham, and Japheth. At the time, Methuselah was 869 and Lamech was 682 years old. Thus, what this means is that Noah’s grandfather and father were alive at the time when Noah had his sons. In other words, Methuselah had lived until Shem, Ham, and Japheth were about 100 years old.
