Your gates will always stand open, they will never be shut, day or night, so that people may bring you the wealth of the nations – their kings led in triumphal procession.
NIV
And your gates shall be open continually, they shall not be shut day or night, that men may bring to you the wealth of the nations--and their kings led in procession [your voluntary captives]. [Rev. 21:24-27.]AMP
Therefore thy gates shall be open continually; they shall not be shut day nor night; that men may bring unto thee the forces of the Gentiles, and that their kings may be brought.
KJV
