Hi Vinton, there's something like this in Genesis 12, of course, but I don't recall anything from Isaiah. If I can think of something else I'll get back to you, but for now, here's the passage from Genesis:
Now the Lord said to Abram, “Go forth from your country, and from your relatives, and from your father’s house, to the land which I will show you; And I will make you a great nation, and I will bless you, and make your name great; And so you shall be a blessing. And I will bless those who bless you, and the one who curses you I will curse. And in you all the families of the earth will be blessed.” (Gen 12:1-3)
Romans 1:11-12-NLT . . .
I long to visit you so I can share a Spiritual Blessing
with you that will help you grow strong in the LORD.
I’m eager to encourage you in your Faith, but I
also want to be encouraged by yours.
In this way, each of us will be a Blessing to the other.
