What were the three promises that god made to abrahàn

Land. First, he promised Abraham a land, a specific location for his people.

Descendants. Secondly, he promised Abraham descendants. And, contextually, that would mean righteous descendants. The wicked are ultimately cut off, and so God's promising Abraham he'll have descendants that will be righteous.

Blessing. And thirdly, he's promising Abraham that the plan related to the first two promises would be blessing to all the nations.
