What were the two promises which God made to Abraham?

God promised Abraham numerous descendants as well as the land of Canaan. Both of these promises are contained in Genesis 15.

1After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward. 2And Abram said, LORD God, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus? 3And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir. 4And, behold, the word of the LORD came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir. 5And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be. 6And he believed in the LORD; and he counted it to him for righteousness. 7And he said unto him, I am the LORD that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.

18In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: 19The Kenites, and the Kenizzites, and the Kadmonites, 20And the Hittites, and the Perizzites, and the Rephaims, 21And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.
