Meditation with Understanding

My mouth shall speak of wisdom; and the meditation of my heart shall be
​of understanding. Psa 49:3
Treasury of David
Charles Haddon Spurgeon

​“My mouth shall speak of wisdom.” Inspired and therefore lifted beyond himself, the prophet is not praising his own attainments, but extolling the divine Spirit which spoke in him. He knew that the Spirit of truth and wisdom spoke through him. He who is not sure that his matter is good has no right to ask a hearing. “And the meditation of my heart shall be of understanding.” The same Spirit who made the ancient seers eloquent, also made them thoughtful. The help of the Holy Ghost was never meant to supersede the use of our own mental powers. The Holy Spirit does not make us speak as Balaam's ass, which merely uttered sounds, but never meditated; but he first leads us to consider and reflect, and then he gives us the tongue of fire to speak with power."

MEDITATION ON LIFE'S BREVITY 
THE FOLLY OF TRUSTING IN RICHES

Psa 49:1  To the chief Musician, A Psalm for the sons of Korah. Hear this, all ye people; give ear, all ye inhabitants of the world: 
Psa 49:2  Both low and high, rich and poor, together. 
Psa 49:3  My mouth shall speak of wisdom; and the meditation of my heart shall be of understanding. 

​Here is a proclamation worthy of the hearing of all the world. The psalmist is listening to voices unheard by ordinary ears. Be sure to listen to God’s voice, and then unfold His dark sayings in music. However dark they may seem in their mystery and awe, they may be uttered in song. See Rev_15:3-4.
The burden of the psalm is the impotence of wealth. The millionaire cannot prolong the life of his sick child. And even if, like Queen Elizabeth, he cries on his dying bed: “A million of money for a moment of time!” the sand passes unheeding through the hour-glass. He must leave stocks and shares, jewels and gold, at the summons of Death, described in Psa_49:14 as the shepherd who calls his flock to fold it in Sheol, R.V. How different the lot of the righteous! As eternity dawns, they are redeemed from the power of the grave and pass to the bosom of God. What are the riches and glory of this world compared with the sense of God’s presence in the humble and contrite heart! To have that is to have the essence of all! “Whom have I in heaven but thee? And there is none upon earth that I desire besides thee. Psa 73:25
