'Heap' in the Bible

When the soles of the feet of the priests carrying the ark of Yahweh, Lord of all the earth, rest in the waters of the Jordan, the waters of the Jordan will be cut off {upstream}, and they will stand [still in] one heap.

the waters flowing down from above stood [still]; they stood up [in] one heap very far from Adam, the city that [is] beside Zarethan, while [the waters] flowing down to the sea of the Arabah, the Salt Sea, {were completely cut off}; and the people crossed [over] opposite Jericho.

So Joshua burned Ai and made it an everlasting heap of rubbish, a desolate place until this day.

The king of Ai he hanged on a tree until the time of evening, and as the sun went down Joshua commanded [them], and they brought down his dead body from the tree. Then they threw it at the entrance of the gate of the city, and they raised over it a great heap of stones [that remains] to this day.
