The Abrahamic Covenant Bible scriptures located in Genesis 22:15-19 explains directly from God's Word the Abrahamic Covenant topic.
And the angel of the LORD called unto Abraham out of heaven the second time,
And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son:
That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies;
And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
So Abraham returned unto his young men, and they rose up and went together to Beersheba; and Abraham dwelt at Beersheba.
