'Numerous' in the Bible

For a nation has invaded our land. There are so many of them they are too numerous to count. Their teeth are like those of a lion; they tear apart their prey like a lioness.

A day of darkness and thick darkness, A day of cloud and thick darkness, As darkness spread on the mountains, A people numerous and mighty, Like it there hath not been from of old, And after it there is not again -- till the years of generation and generation.
