Matthew 1:23 confirms that the prophecy in Isaiah 7:10-14 was fulfilled in Jesus because Jesus is "Immanuel” which is translated as “God with us." Thus, Isaiah 9:6 is a prophecy predicting that the name of the child born and son given would be called the same name as the "Mighty God" and "Eternal Father” (John 17:11, Philippians 2:9, Heb. 1:4). This is why the prophet Jeremiah wrote that the Son "shall be called (future tense), Yahweh our righteousness" (Jer. 23:5-6 – An alleged God the Son should have always been called Yahweh). And this is why Psalm 118:14 says, "Yahweh is my strength and my song, He also has BECOME MY SALVATION."
