Isaiah 7:14; Isaiah 9:6-7

14 Therefore Adonai himself will give you people a sign: the young woman will become pregnant, bear a son and name him 'Immanu El [God is with us].

6 For a child is born to us, a son is given to us; dominion will rest on his shoulders, and he will be given the name Pele-Yo'etz El Gibbor Avi-'Ad Sar-Shalom [Wonder of a Counselor, Mighty God, Father of Eternity, Prince of Peace],

7 in order to extend the dominion and perpetuate the peace of the throne and kingdom of David, to secure it and sustain it through justice and righteousness henceforth and forever. The zeal of ADONAI-Tzva'ot will accomplish this.
