It came about ... the window of the ark which he had made

The phrase "which he had made" tells about the window. Some languages may need to make this phrase a separate sentence: "Noah had made a window in the boat. It came about after forty days that he opened the window" (See: rc://en/ta/man/translate/figs-distinguish)
