Genesis 6:21

And take thou unto thee of all food that is eaten
By man and beast; of which see ( Genesis 1:29 Genesis 1:30 ) and thou shall gather [it] to thee;
to lay up in the ark: and it shall be for food for thee, and for them:
during the flood, a quantity sufficient for them: and according to the calculation of learned men ^F14, well versed in mathematics, there was room enough in the ark, and to spare, to put food for them all during the time the flood was on the earth.
