Because some being deceived worshipped dumb serpents and worthless beasts, thou didst send upon them a multitude of dumb beasts for vengeance. Wisdom 11:16
What was the first thing that Noah did after getting off of the ark?
Kill one of each clean beast and fowl as a burnt offering to God.
And Noah builded an altar unto the LORD; and took of every clean beast,
and of every clean fowl, and offered burnt offerings on the altar. Genesis 8:20
