'Innocency' in the Bible

Said he not himself unto me, She is my sister? And she, even she herself said, He is my brother. In the integrity of my heart and the innocency of my hands have I done this.

I will wash my hands in innocency: So will I compass thine altar, O Jehovah;

Surely in vain have I cleansed my heart, And washed my hands in innocency;

My God hath sent his angel, and hath shut the lions mouths, and they have not hurt me; forasmuch as before him innocency was found in me; and also before thee, O king, have I done no hurt.

He hath cast off thy calf, O Samaria; mine anger is kindled against them: how long will it be ere they attain to innocency?
