The King James Bible addresses trust in several passages:
Proverbs 3:5-6 (KJV)
5 Trust in the LORD with all thine heart; and lean not unto thine own understanding. 6 In all thy ways acknowledge him, and he shall direct thy paths.
Psalms 56:3-4 (KJV)
3 What time I am afraid, I will trust in thee. 4 In God I will praise his word, in God I have put my trust; I will not fear what flesh can do unto me.
Isaiah 26:3-4 (KJV)
3 Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. 4 Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength:
Jeremiah 17:7-8 (KJV)
7 Blessed is the man that trusteth in the LORD, and whose hope the LORD is. 8 For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.
Psalms 37:3-5 (KJV)
3 Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed. 4 Delight thyself also in the LORD: and he shall give thee the desires of thine heart. 5 Commit thy way unto the LORD; trust also in him; and he shall bring it to pass.
