'Forefront' in the Bible

[From] the forefront of the gate at the entrance to the forefront of the inner porch of the gate were fifty cubits.

Then he measured the breadth from the forefront of the lower gate to the forefront of the inner court outside, one hundred cubits, [both] on the east and on the north.

He brought me back to 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.
