6 Noah was six hundred years old when the floodwaters came on the earth. 7 And Noah and his sons and his wife and his sons’ wives entered the ark to escape the waters of the flood. 8 Pairs of clean and unclean animals, of birds and of all creatures that move along the ground, 9 male and female, came to Noah and entered the ark, as God had commanded Noah. 10 And after the seven days the floodwaters came on the earth.
11 In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. 12 And rain fell on the earth forty days and forty nights.
13 On that very day Noah and his sons, Shem, Ham and Japheth, together with his wife and the wives of his three sons, entered the ark. 14 They had with them every wild animal according to its kind, all livestock according to their kinds, every creature that moves along the ground according to its kind and every bird according to its kind, everything with wings. 15 Pairs of all creatures that have the breath of life in them came to Noah and entered the ark. 16 The animals going in were male and female of every living thing, as God had commanded Noah. Then the LORD shut him in.
Everything happens just as God said it would. Water comes from below and above (v11). Surrounded from all sides.
All enter the ark – Noah and his wife and his sons and his son’s wives, all the creatures, domestic and wild, flying or walking, both clean and unclean. Everybody is where they are supposed to be. The creatures ‘came to Noah’ and entered the ark. They, too, acted in obedience.
And God shut him in
God does the final closing of the door, a protective touch. (In other flood stories of the surrounding area, the man closes the door to keep the gods’ wrath out – this is a touching reversal.) The humans and the animals and the birds and ‘everything that crawls on the ground’ – is this reptiles? Insects? Everything and anything else?
The floodgates open and the door is closed. Now – to survive.
