Genesis 7:1
1 The Lord said to Noah, “Come into the ark, you and all your household, for I consider you godly among this generation. 2 You must take with you seven pairs of every kind of clean animal, the male and its mate, two of every kind of unclean animal, the male and its mate, 3 and also seven pairs of every kind of bird in the sky, male and female, to preserve their offspring on the face of the entire earth.
Exodus 2:3
1 A man from the household of Levi married a woman who was a descendant of Levi. 2 The woman became pregnant and gave birth to a son. When she saw that he was a good child8, she hid him for three months. 3 But when she was no longer able to hide him, she took a papyrus basket for him and sealed it with bitumen and pitch. She put the child in it and set it among the reeds along the edge of the Nile. 4 His sister stationed herself at a distance to find out what would happen to him.
Notes and References
"... Genesis 7:1 ... The Hebrew means a “box.” It has long been translated as “ark,” which is the Old English word for “box.” Because “ark” is so old an English word, which people no longer use in daily speech and writing and because the story is so famous, people frequently think that the word really means “boat.” It is not a boat in the flood story. The same applies to the box in which the baby Moses is placed in Exodus 2:3. Still, I must admit that it is notable that the two objects called “ark” in the Hebrew Bible both float on water. I have used the word “ark” here reluctantly because it is now so familiar that readers would find any other word jarring, and it might distract them from the flow of the story ..."
