Psalms 45:1 - Exposition

My heart is inditing a good matter ; literally, bubbleth with a good matter —is so full of it that the matter will burst forth. I speak of the things which I have made touching the king ; or, I utter that which I have composed concerning the king. My tongue is the pen of a ready writer . It is noted that only "psalms of high and solemn import" have formal exordia of this kind, announcing the intention of the writer.
