“Praise ye the LORD. Sing unto the LORD a new song, and His praise in the congregation of saints.” Psalm 149:1 (KJV)
Singing and making melody in your heart to the Lord is one of the evidences of the filling of the Holy Spirit in a Believer’s life (Ephesians 5:18-21 note v. 19).
There are a few references to a “New song” in Scripture. They are Psalm 33:3; 40:3; 96:1; 98:1; 144:9; 149:1 (the above verse); Isaiah 42:10; Revelation 5:9; and 14:3.
Hallelujah. Praise the LORD. Those who trust Him and know Him have a new song to sing. Let us sing it when we are alone with Him. Let us sing it when we are meeting together a congregations of Believers.
Sing unto the LORD a new song. Sing, sing, sing.
