Ether 2:17

and they were built after a manner that they were exceeding tight, even that they would hold water like unto a dish; and the bottom thereof was tight like unto a dish; and the sides thereof was tight like unto a dish; and the ends thereof were peaked; and the top thereof was tight like unto a dish; and the length thereof was the length of a tree; and the door thereof, when it was shut, was tight like unto a dish.

They were built so they were very tight. They would hold water like a dish. The bottom was tight like a dish. The sides were tight like a dish. The ends were pointed. The top was tight like a dish. They were as long as a tree. When the door was shut, it was tight like a dish.

They were built to be completely watertight, like a bowl. The bottom was sealed like a bowl. The sides were sealed like a bowl. The ends came to points. The top was sealed like a bowl. They were as long as a tree. And the door, when shut, was sealed like a bowl.
