In Matthew’s passage about the Triumphant Entry, he quotes from and links to Psalm 118. It is likely that Jesus sang this Psalm, along with the other Hallel Psalms (Pss. 113-18), with the disciples after He instituted the Lord’s Supper (Mk. 14:26). That’s not surprising since Psalm 118 highlights God’s steadfast love and has many Christ connections.
Psalm 118 talks about the gate that the righteous enter through to go into the presence of God (v. 20). That is not a gate that we can open on our own because we cannot be righteous on our own (Rom. 3:10). Actually, the Bible says even the best we can do on our own is like filthy rags (Is. 64:6). We need the righteousness of Jesus Christ (Heb. 10:19-22). Jesus is the gate that gives us access to God the Father (Jn. 14:6), He is the one that makes us righteous.
Jesus was the rejected stone (Matt. 21:42) but He is the Messiah, the cornerstone (Ps. 118:22). All promises rest upon Him (2 Cor. 1:20). When Jesus made His way to Jerusalem, the people cried out: “Hosanna! Save us, we pray, O LORD!” (Matt. 21:9). The people spoke better than they knew. They cried out to Jesus who is God in flesh to save—and He soon would. He would fulfill their prayer to save by answering the next cry of the crowds, that He be crucified.
The Psalm says, “The LORD is God, and He has made His light to shine upon us” (Ps. 118:27). Truly. God in flesh dwelt among us. And yet He was the “festal sacrifice” (v. 27). Jesus is finally triumphant not by overthrowing the Roman government but by overthrowing Satan, sin, and death through His death and resurrection.
