'Secrecy' in the Bible

I have spoken not in secrecy, in a place, a land, of darkness, I have not said to the descendants of Jacob, 'Seek me {in vain}!' I, Yahweh, [am] speaking righteousness, declaring uprightness.

Draw near to me; hear this! I have not spoken in secrecy from [the] {beginning}; from [the] time {it came to be}, there I [have been]; And now the Lord Yahweh has sent me and his Spirit."
