Heb 7:3 Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.
To be without descent, to have neither beginning of days, nor end of life, and to be made like the Son of God is to be God.
Isa 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor,
The mighty God, The everlasting Father, The Prince of Peace.
Heb 7:2 To whom also Abraham gave a tenth part of all; first being by interpretation

Jesus is the Mighty God. Jesus and the Father are one.
Jos 5:14 And he said, Nay; but
as captain of the host of the LORD am I now come. And Joshua fell on his face to the earth, and did worship, and said unto him, What saith my lord unto his servant?
