Jesus came for the lost sheep of the house of Israel: The physical seed of Abraham OR children of the promise?

Romans 9:8 KJV

That is, They which are the children of the flesh, these are NOT the children of God: but the children of the promise are counted for the seed.

Matthew 10:6 KJV

"But go rather to the lost sheep of the house of Israel."

(Never go unto the Gentiles OR don't go...yet?)

Rom 11:13-15 KJV

For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
If by any means I may provoke to emulation them which are my flesh, and might save some of them.
For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?

Isaiah 49:6 KJV

And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth.
