Even if Matthew 28:19 were omitted, Christ's command to preach to all nations is clearly stated in Mark 16:15. :
And it is further supported by Acts 1:6-8. :And he said to them, â€œGo into all the world and proclaim the gospel to the whole creation."
You said:So when they had come together, they asked him, "Lord, will you at this time restore the kingdom to Israel?" He said to them, "It is not for you to know times or seasons that the Father has fixed by his own authority. But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth."
