Anag - Delight- This is a rather surprising word. It gives an image of luxurious softness and pure pleasure. Picture sinking into soft satin sheets and being waited on. This is the type of pleasure we should get when we spend time with YHVH.
Nathan - Give- This word simply means to give as a gift.
Mish alah - Desires- The base of this word is to draw out. It can refer to the spoils of battle, prosperity, or unknown knowledge.
Lev - Heart- In Hebrew thought, the heart is the center of our being, our inside authority, or base for wisdom, understanding, and thought.
To put this verse in a more Hebrew context, it might look like this.
When you spend time with YHVH, bask in the luxurious and rich experience of being in His presence. Receive each bit of wisdom as a gift. Find your wholeness and completeness in Him. Then He will surprise you, and give you gifts far beyond what you can imagine. He will search your deepest being, the part of you that you barely know. He knows the part of you that you dare not share with anyone else. He knows what you always dreamed of, but feared you would never realize. He delights in giving you those very things that you thought you would never see. He also wishes to give you wisdom, understanding, and peace. He will make your desires His desires as you delight in Him. And you will be overwhelmed, because all you really needed was the beauty of His presence.
