'Heap' in the Bible

When the soles of the feet of the priests who carry the ark of the Lord, the Lord of all the earth, [come to] rest in the waters of the Jordan, the waters of the Jordan flowing down from above will be cut off, and they will stand in one mass [of water].”

the waters which were flowing down from above stopped and rose up in one mass a great distance away at Adam, the city that is beside Zarethan. Those [waters] flowing downward toward the sea of the Arabah, the Salt Sea, were completely cut off. So the people crossed [the river] opposite Jericho.

Then they piled up over him a great heap of stones that remains to this day. Then the Lord turned from the fierceness of His anger. Therefore the name of that place has been called the Valley of Achor (Disaster) to this day.

So Joshua burned Ai and made it a rubbish heap forever, a desolation until this day.

He hanged [the body of] the king of Ai on a tree [leaving it there] until evening; at sunset Joshua gave a command and they took the body down from the tree and dumped it at the entrance of the city gate, and piled a great heap of stones over it that stands to this day.
