'In the Darkness' in the Bible

What I am telling you in the darkness [i.e., in obscurity], you tell it in the light [i.e., openly]. And what you hear [whispered] in your ear [you should] declare it from the housetops.

Therefore, whatever you have said in the darkness [i.e., in obscurity] will be heard in the light [i.e., openly]. And what you have whispered in someone's ear in a back room, will be declared from the housetops.

And [His] light continued to shine, [even] in the darkness [of the world], and that darkness did not overcome Him [or, did not fully understand Him].

The person who claims to be living in [harmony with] the light [i.e., by obeying God's truth], and [yet] hates his brother is still [living] in the darkness [of sin].

But the person who hates his brother is in the darkness [of sin] and he lives in [harmony with] that darkness, and he does not know where he is heading, because the darkness [of sin] has blinded his eyes [to his spiritual condition].
