Psalm 37:4 in the King James Version reads, “Delight thyself also in the LORD; and he shall give thee the desires of thine heart.” In its plain sense, the verse joins a command and a promise: the life that takes its pleasure, satisfaction, and resting joy in “the LORD” is the life in which God answers the deepest longings of the “heart.” Yet its full meaning is best heard inside the psalm’s larger message and in the spiritual logic that binds delight and desire together.

Psalm 37 is a psalm “of David” that speaks like wisdom, patiently teaching how to live when evil seems to prosper. It opens with counsel against envy and agitation: “Fret not thyself because of evildoers” and “neither be thou envious against the workers of iniquity” (Psalm 37:1). The reason is not denial of present injustice but confidence in God’s end: “For they shall soon be cut down like the grass” (Psalm 37:2). Into that setting, Psalm 37:4 is not a standalone slogan about getting what one wants; it is part of a sequence of holy remedies for a troubled soul. Just before it, David says, “Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed” (Psalm 37:3). Immediately after it, he adds, “Commit thy way unto the LORD; trust also in him; and he shall bring it to pass” (Psalm 37:5), and then, “Rest in the LORD, and wait patiently for him” (Psalm 37:7). Taken together, these lines show that “delight” is not momentary religious emotion but a settled posture of faith, obedience, surrender, and patient waiting in God.

The first half of the verse, “Delight thyself also in the LORD,” addresses the inner life, the place where fretting and envy begin. To “delight” is to choose God Himself as one’s portion and joy, to value His presence and His ways above the apparent advantages of the wicked. In the psalm’s context, delight is a direct alternative to the bitter pleasure of comparison. The soul that delights in the LORD refuses to measure reality merely by what the eye sees in the short term. This delight is not escapism; it is anchoring. It is the heart turning from “evildoers” to the LORD, from unstable circumstances to the character of God, from anxious grasping to worshipful contentment. The small word “also” matters because David is stacking graces: trust, doing good, delight, commitment, rest, waiting. Delight is “also,” not instead of. It belongs with a faithful life, not with a passive one.

The second half, “and he shall give thee the desires of thine heart,” speaks to God’s answer, but it must be read in the light of what the heart becomes when it truly delights in the LORD. In Scripture, the “heart” is not merely feelings; it is the center of desire, will, and purpose. When a person’s delight is in God, the heart is reshaped. Desires that once ran toward envy, quick gain, revenge, or self-exaltation are purified and redirected. In that sense, the promise is not only that God grants what the heart wants, but that God, by becoming the heart’s delight, forms the very wants that He delights to grant. The verse holds a quiet, profound symmetry: delight in the LORD and desires of the heart belong together because delight governs desire. A heart that truly delights in the LORD comes to desire what is fitting to His fellowship, and the LORD is not stingy toward such desires.

This is why Psalm 37 repeatedly emphasizes inheritance, stability, and enduring blessing rather than flashy, immediate success. The wicked may seem to flourish, but “the LORD knoweth the days of the upright: and their inheritance shall be for ever” (Psalm 37:18). The righteous may have “a little,” yet “a little that a righteous man hath is better than the riches of many wicked” (Psalm 37:16). In this setting, “the desires of thine heart” are not chiefly about mimicking the apparent “riches” of the wicked; they are about the deeper longings for God’s vindication, God’s provision, God’s peace, and God’s faithful guidance. The psalm even points to a desire greater than circumstances: “The steps of a good man are ordered by the LORD: and he delighteth in his way” (Psalm 37:23). The LORD is not merely a means to an end; He is the end in which the soul delights, and from that delight flows a life ordered and upheld by God: “though he fall, he shall not be utterly cast down: for the LORD upholdeth him with his hand” (Psalm 37:24).

There is also symbolism in the psalm’s repeated contrasts. The wicked are likened to grass that withers: “they shall soon be cut down like the grass, and wither as the green herb” (Psalm 37:2). Grass is vivid for a moment and then gone; it symbolizes the fragile, temporary nature of unrighteous prosperity. Against that fading greenness stands the enduring gift implied in Psalm 37:4: the LORD giving. The world’s “giving” is often unstable, taken away by time, chance, or judgment. God’s giving, especially to the heart that delights in Him, has the character of covenant faithfulness. Even when the desire is something outward, the psalm’s overall symbolism suggests that what lasts is what is rooted in the LORD’s steadfast care, not what is seized by anxious striving.

Psalm 37:4 is therefore significant as a doorway into a different way of wanting. It teaches that the cure for fretting is not the suppression of desire but the sanctification of desire through delight in God. It invites the reader to make the LORD the soul’s pleasure and treasure, so that the heart’s cravings are no longer enslaved to what evildoers appear to have, but are tuned to what God loves to bestow. In a world where the wicked may “prosper in his way” (Psalm 37:7), this verse speaks of a deeper prosperity: a heart satisfied in God and, from that satisfaction, a life in which God faithfully provides what that renewed heart truly seeks.
