1. In verses 2 and 3, God instructs Noah to take seven of each clean animal and of the birds, but only two of each unclean animal. Then, in verses 8 and 9, Noah takes two of each animal. Why is there a difference in numbers? Why did God differentiate between the different species?
"You shall take with you seven of each of every clean animal, a male and his female; two each of animals that are unclean, a male and his female; also seven each of birds of the air, male and female, to keep species alive on the face of the earth." (v. 2-3)
"Of clean animals, of animals that are unclean, of birds, and of everything that creeps on the earth, two by two they went into the ark to Noah, male and female, as God had commanded Noah." (v. 8-9)
2. Is the number, one hundred and fifty, significant at all?
"And the waters prevailed on the earth one hundred and fifty days." (v. 24)
