A grasp of why this is important requires a background of understanding, but the thumbnail lies in Genesis 12
Now the Lord said to Abram,
“Go out from your country, your relatives, and your father’s household to the land that I will show you. Then I will make you into a great nation, and I will bless you, and I will make your name great, so that you will exemplify divine blessing. I will bless those who bless you, but the one who treats you lightly I must curse, so that all the families of the earth may receive blessing through you.”
— Genesis 12:1-3
