Berean Standard Bible (BSB)
The side rooms surrounding the temple widened at each successive level, because the structure surrounding the temple ascended by stages corresponding to the narrowing of the temple wall as it rose upward. And so a stairway went up from the lowest story to the highest, through the middle one.
World English Bible (WEB)
The side rooms were broader as they encompassed the house higher and higher; for the encompassing of the house went higher and higher around the house: therefore the breadth of the house continued upward; and so one went up from the lowest room to the highest by the middle room.
Strong's King James
And there was an enlarging{H7337}{(H8804)}, and a winding about{H5437}{(H8738)} still upward{H4605} to the side chambers{H6763}: for the winding about{H4141} of the house{H1004} went still upward{H4605} round about{H5439} the house{H1004}: therefore the breadth{H7341} of the house{H1004} was still upward{H4605}, and so increased{H5927}{(H8799)} from the lowest{H8481} chamber to the highest{H5945} by the midst{H8484}.

Young's Literal Translation
And a broad place and a turning place still upwards are to the side-chambers, for the turning round of the house is still upwards all round about the house: therefore the breadth of the house is upwards, and so the lower one goeth up unto the higher by the midst.
