isaiah 57:11 And of whom hast thou been afraid or feared, that thou hast lied, and hast not remembered me, nor laid it to thy heart? have not I held my peace even of old, and thou fearest me not? - Free Bible Online

      11. Israel wished not to seem altogether to have denied God. Therefore they "lied" to Him. God asks, Why dost thou do so? "Whom dost thou fear? Certainly not Me; for thou hast not remembered Me." Translate, "seeing that thou hast not remembered Me."
      laid it to . . . heart--rather, "nor hast Me at heart"; hast no regard for Me; and that, because I have been long silent and have not punished thee. Literally, "Have I not held My peace, and that for long? and so thou fearest Me not" (Ps 50:21; Ec 8:11). It would be better openly to renounce God, than to "flatter Him" with lies of false professions (Ps 78:36) [LUDOVICUS DE DIEU]. However, Isa 51:12, 13 favors English Version of the whole verse; God's "silent" long-suffering, which was intended to lead them to repentance, caused them "not to fear Him" (Ro 2:4, 5).
