The King James Version addresses anxiety and worry through direct instruction to cast cares on God and receive his peace.
6Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.7And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
25Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?26Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?27Which of you by taking thought can add one cubit unto his stature?
34Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
6Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time:7Casting all your care upon him; for he careth for you.
22Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved.
19In the multitude of my thoughts within me thy comforts delight my soul.
10Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.
27Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
25Heaviness in the heart of man maketh it stoop: but a good word maketh it glad.
7For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
4I sought the LORD, and he heard me, and delivered me from all my fears.
