A kind of bitumen. Noah covered the ark with pitch inside and outside. Genesis 6:14 . The ark in which the infant Moses was put, was likewise thus rendered waterproof. Exodus 2:3 . Among God's judgements on the earth the streams are turned into pitch, and the land into burning pitch. Isaiah 34:9 . Different words are employed in the Hebrew of Genesis 6:14 from the other passages. Noah was to pitch ( kaphar , 'to cover,' often translated 'atonement') the ark with pitch (kopher, translated 'ransom') as if to teach that Noah and those with him could be saved only by being covered with a ransom, and which would introduce them to a new earth.
