I will sing with the spirit, and I will sing with the understanding also. -- I COR.14:15.

Be filled with the Spirit, speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord. -- Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.

My mouth shall speak the praise of the Lord: and let all flesh bless his holy name for ever and ever.

Praise ye the Lord: for it is good to sing praises unto our God; for it is pleasant; and praise is comely. Sing unto the Lord with thanksgiving; sing praise upon the harp unto our God.

I heard a voice from heaven, as the voice of many waters, and as the voice of a great thunder; and I heard the voice of harpers harping with their harps.
