Isaiah 7:14-16

New Catholic Bible

¹⁴ Therefore, you will be given this sign
    by the Lord himself:
The virgin will be with child,
    and she will give birth to a son,
    and she will name him Immanuel.
¹⁵ He will feed on curds and honey
    by the time he learns to reject the bad
    and choose the good.
¹⁶ Before that child has learned
    to reject the bad and choose the good,
deserted will be the lands
    of those two kings whom you dread.
