Isaiah 38:3

38:3 “Please, Lord. Remember how I have served you faithfully and with wholehearted devotion, and how I have carried out your will.” Then Hezekiah wept bitterly.

Isaiah 47:12

47:12 Persist in trusting your amulets

and your many incantations,

which you have faithfully recited since your youth!

Maybe you will be successful –

maybe you will scare away disaster.

Isaiah 47:15

47:15 They will disappoint you,

those you have so faithfully dealt with since your youth.

Each strays off in his own direction,

leaving no one to rescue you.”
