For Zion's sake will I not hold my peace, and for Jerusalem's sake I will not rest, until the righteousness thereof go forth as brightness, and the salvation thereof as a lamp that burneth.

Thou shalt be called by a new name - Viz., Christian - or, as in the fourth verse, חפצי בה chephtsi bah, "my delight is in her" - because she has now received that command, "This is my beloved Son, in whom I am well pleased; Hear Him."
