In the sixth chapter of Genesis we are told that the wickedness of mankind was great and would bring about its destruction, but that "Noah found grace in the eyes of the Lord.
...And Noah walked with God." The patriarch listened for God's voice and, having heard it, obeyed. This message instructed Noah to build an ark of gopher wood and of a certain size and shape, and to pitch it inside and out. It is interesting to note that the word translated "pitch" is "kaphar," a Hebrew word which is also figuratively translated "to make atonement."
Our dear Leader, Mary Baker Eddy, tells us on page 18 of the Christian Science textbook, "Science and Health with Key to the Scriptures," that "atonement is the exemplification of man's unity with God, whereby man reflects divine Truth, Life, and Love." The word "ark" in the Hebrew is "tebah." The same word was used for the "ark" in which Moses was hid. The word translated "ark," used elsewhere, means chest, coffer, or repository.
