'Soles' in the Bible

Every place that the soles of your feet will tread, I have given it to you, as I promised to Moses.

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.

And it happened that when the priests carrying the ark came up from the middle of the Jordan, and the soles of the priests' feet {touched dry land}, the waters of the Jordan returned to their place and flowed over all its banks as before.
