In Genesis, who shut Noah and his family inside the Ark?

In Genesis, the LORD shut Noah and his family inside the Ark.

Genesis 7:16 says that those entering the Ark included Noah, his wife, his sons, and his sons’ wives, along with the animals, and then states that the LORD shut him in. The wording gives the closing of the Ark a direct divine action rather than presenting it as an ordinary task performed by Noah.

This detail occurs immediately before the Flood waters rise. It reinforces the narrative’s emphasis on protection and divine control: Noah builds the Ark according to instructions, gathers those designated for survival, and then the door is closed by God.

Some retellings say simply that Noah closed the door, because he is the human builder and central character. Genesis itself makes a more specific statement about who shut the Ark. The passage also does not name a separate doorkeeper or angel in this scene.
