We cast our burden upon the Lord
Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved. (Psalm 55:22 KJV)

Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light. (Matthew 11:28-30 KJV)

Casting all your care upon him; for he careth for you. (1 Peter 5:7 KJV)
