'Henceforth' in the Bible

To the increase of the princely power, And of peace, there is no end, On the throne of David, and on his kingdom, To establish it, and to support it, In judgment and in righteousness, Henceforth, even unto the age, The zeal of Jehovah of Hosts doth this.

And I -- this is My covenant with them, said Jehovah, My Spirit that is on thee, And My words that I have put in thy mouth, Depart not from thy mouth, And from the mouth of thy seed, And from the mouth of thy seed's seed, said Jehovah, From henceforth unto the age!
