1
At that time, after the death of Methuselah, the Lord said to Noah,
Go thou with thy household into the ark; behold I will gather to thee all the animals
of the earth, the beasts of the field and the fowls of the air, and they shall all come
and surround the ark.
2
And thou shalt go and seat thyself by the doors of
the ark, and all the beasts, the animals, and the fowls, shall
assemble and place themselves before thee, and such of them as shall
come and crouch before thee, shalt thou take and deliver into the hands of
thy sons, who shall bring them to the ark, and all that will stand before
thee thou shalt leave.
3
And the Lord brought this about on the next day, and animals,
beasts and fowls came in great multitudes and surrounded the ark.
4
And Noah went and seated himself by the door
of the ark, and of all flesh that crouched before him, he brought
into the ark, and all that stood before him he left upon earth.
Chapter VI also mentions that
the ark was still surrounded by animals when 700,000 people came to try to break into the ark. These
animals attacked the 700,000 people. This is mentioned in verses 16 & 17 and verses 24 & 25. These verses read:

And the sons of men assembled together, about seven hundred
thousand men and women, and they came unto Noah to the ark.

to come in on account of the rain, for they could not bear the rain upon them.

the ark. And the beasts overpowered them and drove them from that place, and
every man went his way and they again scattered themselves upon the face of the earth.
