Casting, to throw away, to discard, to abandon, to throw off, to eject ...okay so let's get rid of somethings! Which things? Worries, cares, anxieties, troubles, "drama", irritations, annoyances, vexations, harassments, uneasiness, distresses, worry over insignificant details, if I could have, would have, should haves. Burdens ! Yokes ! Distasteful experiences! That which is "bugging" you ! Questions for which you have NO answer !

1 Peter 5:7 King James Version (KJV)

7 Casting all your care upon him; for he careth for you.
