'Forefront' in the Bible

And from the forefront of the gate at the entrance unto the forefront of the inner porch of the gate were fifty cubits.

Then he measured the breadth from the forefront of the lower gate unto the forefront of the inner court without, a hundred cubits, both on the east and on the north.

And he brought me back unto the door of the house; and, behold, waters issued out from under the threshold of the house eastward; (for the forefront of the house was toward the east;) and the waters came down from under, from the right side of the house, on the south of the altar.
