Short answer: Psalm 55:22 means you can deliberately hand your crushing worries and burdens over to God, and he will hold you up under them. "Cast" is an act of release — throwing the weight off yourself and onto the One strong enough to carry both it and you.
The context
Psalm 55 is a psalm of David written in deep distress. He describes his heart being "in anguish" (v.4), terror and trembling (v.5), and — most painfully — betrayal by a close friend who had walked with him in worship (vv.12-14). This is a verse born out of genuine crisis, not calm reflection. After pouring out his fear and hurt, David lands in verse 22 on a resolution: he will give the weight to God.
What it means, phrase by phrase
"Cast thy burden upon the Lord" (KJV; WEB: "Cast your burden on Yahweh"). "Cast" is an active, decisive verb — to throw or hurl. It pictures lifting the heavy thing off your own shoulders and flinging it onto God. "Burden" is whatever weighs you down: anxiety, grief, responsibility, betrayal. The instruction is not to carry it more bravely but to transfer it.
"and he shall sustain thee." "Sustain" means to hold up, support, provide for. God doesn't just take the burden; he holds up the person. The promise is stability — being kept steady rather than collapsing under the weight.
"he shall never suffer the righteous to be moved." "Moved" means shaken loose or toppled. God will not let those who trust him be permanently overthrown. It is not a promise of an easy life, but of a secure footing.

How to apply it today
The key word is cast — an intentional act, not a vague hope. Worry often means picking a burden back up again and again. This verse invites a concrete practice: name the specific weight, and in prayer consciously hand it over to God, refusing to carry what he has offered to hold. When the anxiety returns (and it will), cast it again.
The promise attached is not that the burden vanishes but that you will be sustained — held steady and not toppled — while God carries it.
Frequently Asked Questions
What does "cast your burden" actually mean? "Cast" means to throw or hurl decisively. It pictures deliberately transferring the weight off your own shoulders onto God, rather than merely trying to bear it more patiently. It's an act of release, often expressed through honest prayer.
How does Psalm 55:22 relate to 1 Peter 5:7? Peter almost certainly draws on this verse when he writes "casting all your anxieties on him, because he cares for you." The New Testament passage adds the reason behind the instruction: God cares for you personally, so you can safely hand him your worries.
Does "sustain you" mean God removes the problem? Not necessarily. "Sustain" means to hold up and support. The promise is that God will keep you steady and unshaken while you go through the burden, not that the difficulty will immediately disappear.
