'Populous' in the Bible

But his father refused and said, “I know, my son, I know! He too will become a tribe, and he too will be great; nevertheless, his younger brother will be greater than he, and his offspring will become a populous nation.”

You are to respond by saying in the presence of the Lord your God:My father was a wandering Aramean. He went down to Egypt with a few people and lived there. There he became a great, powerful, and populous nation.
