King James Version (KJV) - Ezekiel 41:7 >

And [there was] an enlarging, and a winding about still upward to the side chambers: for the winding about of the house went still upward round about the house: therefore the breadth of the house [was still] upward, and so increased [from] the lowest [chamber] to the highest by the midst.

Jewish Publication Society of America Version (JPS1917) - Ezekiel 41:7 >

And the side-chambers were broader as they wound about higher and higher; for the winding about of the house went higher and higher round about the house; therefore the breadth of the house continued upward; and so one went up from the lowest row to the highest by the middle.
