Hope that is deferred makes the heart sick, but a desire fulfilled is a tree of life.
Let’s look at some words here to get into the meaning. Hope does not mean, to Wish.
Hope: comes from the Hebrew word to-kheh'-leth, it means expectation. Which comes from the primitive root word:
yâchal - yaw-chal'
Which means: by implication to be patient, stay, trust, wait.
Now we see that the word Hope means that we are patiently expecting. What then are we expecting? The desired outcome, you can’t hope for a bad outcome, now can you? But I suppose if you have an evil heart you can. Never the less,
Deferred comes from the Hebrew word
mâshak - maw-shak'
To draw, and is used in a great variety of applications including to sow, to sound, to prolong, to develop, to continue, to scatter, to stretch out.
Now suddenly this has become a very interesting word usage.
To sound: basically means to take a line and drop it over the side of a boat and see how deep the water is. To measure the depths of the water.
Stretch out: Why would God stretch out your expectancy? To see your heart.
lêb - labe
Also used very widely for the feelings, the will and even the intellect; likewise for the center of anything: The center of your emotions, will, strength, understanding, wisdom, and mind.
châlâh - khaw-law'
Properly to be rubbed or worn (polished,) to be weak, sick, afflicted;
to grieve, to be sorry, to be wounded.
We’ll come back to this word later…
ta'ăvâh - tah-av-aw'
A longing; by implication a delight, desire, exceedingly, pleasant.
Lets take a look at:
Delight thyself also in the LORD; and he shall give thee the desires of thine heart.
Now we take this verse and we can see the effects of the first verse Proverb 13:12. By combining these two verses together for an expectation. When God gives you the desires of your heart this has a dual message.
First: He places that desire in your heart.
Second: He gives you that desire.
So why would God give you a desire and then allow it to be delayed?
Remember the word sick, to be rubbed or worn (or polished)
As I was typing this, I saw a vision of the Holy Spirit polishing a vessel, what I interpret this to mean is that God wants to see the true beauty of your heart, not as we negatively think, that He is trying to uncover the wickedness of your heart, but the beauty. You never polish a vessel to see the damage, but to reveal the beauty.
Let’s put all this together:
Hope (your expectancy by being patient: will make you to trust, and wait.) that is deferred (To sound: God will take a line and drop it into your heart see how deep your heart is, using His line as a marker to determine the depths of your heart. God will stretch out your expectancy, He does this to get to the true goodness of your heart) makes the heart sick, (As if the Holy Spirit is polishing your heart, to present it to God so that He can see the true beauty of your heart, not the wickedness but the beauty) but a desire (a delight, exceedingly, pleasant thing or need) fulfilled is a tree of life. (That allows you to tap into the very deep springs of God’s living waters, to receive sustenance and life freely from Him, to know His true goodness.)
He is: "YAHUAH TSIDQENU"
The Lord our righteousness"
