"There Is One God And One Mediator Between God And Men, The Man Christ Jesus" 
1 Timothy (2:5)

Does the Bible say that Jesus was God with us? Matthew 1:23

No. (Matthew 1:23)

First, the name Jesus is not mentioned.

Second, It is not indicating “what” the son would be (i.e, God or a man) but rather what the interpretation of the word Emanuel “means.”

Third, it is an accurate reflection of the truth, because God was with Christ and in Christ (John 14:10-11; Acts 10:38; 2Cor 5:19) but God was certainly not the root of David as was Jesus (John 7:42; Rom 1:3; 2Tim 2:8; Rev 22:16).
