Seed and Stars and Sand

Gen 22:15 And the angel of the LORD called unto Abraham out of heaven the second time,
Gen 22:16 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:
Gen 22:17 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;
Gen 22:18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
Gen 22:19 So Abraham returned unto his young men, and they rose up and went together to Beersheba; and Abraham dwelt at Beersheba.
Gen 22:20 And it came to pass after these things, that it was told Abraham, saying, Behold, Milcah, she hath also born children unto thy brother Nahor;
Gen 22:21 Huz his firstborn, and Buz his brother, and Kemuel the father of Aram,
Gen 22:22 And Chesed, and Hazo, and Pildash, and Jidlaph, and Bethuel.
Gen 22:23 And Bethuel begat Rebekah: these eight Milcah did bear to Nahor, Abraham's brother.
Gen 22:24 And his concubine, whose name was Reumah, she bare also Tebah, and Gaham, and Thahash, and Maachah.
