In today's study from Matthew 1:1, we see that Jesus was uniquely qualified to be the fulfillment of both the Davidic and Abrahamic Covenants.
The Davidic Covenant
Jesus was to be and will yet future be the fulfillment of the Davidic Covenant because is qualified to fulfill that promise (cf. 2 Sam. 7:12-16). Now portions of this are speaking of Solomon, but it is ultimately looking to Christ. The Bible is clear that Jesus is King, has a throne and a kingdom.
He is declared king in the book of Matthew (Cf. Matt. 2:2). The Bible also says in Matthew 27:37 And they put up over His head the accusation written against Him: THIS IS JESUS THE KING OF THE JEWS.
Given a Throne
He has been given a throne. It was said of him in Luke 1:32, He will be great, and will be called the Son of the Highest; and the Lord God will give Him the throne of His father David.
Given a Kingdom
He has been given a Kingdom. Jesus said in Luk 23:42 "Lord, remember me when You come into Your kingdom."
The Abrahamic Covenant
Also, Matthew wanted to clearly demonstrate that Jesus was a son of Abraham, and not only met the requirements of the covenant but will also fulfill it one day (Cf. Genesis 12:1-3; 17:1-13).
Jesus was circumcised
Jesus kept the sign of the covenant which was circumcision. We are told in Luke 2:21 And when eight days were completed for the circumcision of the Child, His name was called JESUS, the name given by the angel before He was conceived in the womb.
Jesus was the Promised Seed
Paul says Jesus was the promised seed and thus the fulfillment of the Abrahamic Covenant when he said in Gal 3:16 Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as referring to many, but rather to one, "And to your seed," that is, Christ. He is not referring to the “seed” of Genesis 15, but to the “seed” of Gen. 22:17-18.
