What are some common trinitarian interpretations of Isaiah 7:14-16

I was doing my morning prayer in the Liturgy of the Hours and this passage appeared: > “Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. He shall eat curds and honey when he knows how to refuse the evil and choose the good. For before the boy knows how to refuse the evil and choose the good, the land whose two kings you dread will be deserted.” ‭‭Isaiah‬ ‭7‬:‭14‬-‭16‬ ‭ESV‬‬ Now I’m particularly confused about how trinitarians read this passage, as it’s commonly used as a citation for Jesus’ incarnation, but this bit about him coming to **know** (implied by before he knows) seems to be problematic for an incarnate deity. What is the trinitarian interpretation of this passage?
