Genesis 6:21
And take thou unto thee of all food that is eaten, and thou shalt gather it to thee; and it shall be for food for thee, and for them.
And take thou unto thee of all food that is eaten,.... By man and beast; of which see Genesis 1:29
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 {n}, 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.
