1 Kings 6:3

And the porch in front of the temple—twenty cubits [was] its length according to the breadth of the house in front of the house: and he built the house, and finished it.

And the porch before the temple of the house, twenty cubits was the length thereof, according to the breadth of the house; and ten cubits was the breadth thereof before the house.

The porch in front of the temple of the house had a length of twenty cubits, which was along the width of the house. Ten cubits was its width in front of the house.
