Lukas 8:17

8:17 For nothing is hidden ¹  that will not be revealed, ²  and nothing concealed that will not be made known and brought to light.

Lukas 12:3

12:3 So then ³  whatever you have said in the dark will be heard in the light, and what you have whispered ⁴  in private rooms ⁵  will be proclaimed from the housetops. ⁶ 

[8:17]  ¹ sn Nothing is hidden. Light also exposes, and Jesus was suggesting that his teaching likewise revealed where people are and where they will be. Truth will be manifest in the future, just as it was declared by him then. Nothing will be concealed.

[8:17]  ² tn Or “disclosed.”

[12:3]  ³ tn Or “because.” Understanding this verse as a result of v. 2 is a slightly better reading of the context. Knowing what is coming should impact our behavior now.

[12:3]  ⁴ tn Grk “spoken in the ear,” an idiom. The contemporary expression is “whispered.”

[12:3]  ⁵ sn The term translated private rooms refers to the inner room of a house, normally without any windows opening outside, the most private location possible (BDAG 988 s.v. ταμεῖον 2).

[12:3]  ⁶ tn The expression “proclaimed from the housetops” is an idiom for proclaiming something publicly (L&N 7.51). Roofs of many first century Jewish houses in Judea and Galilee were flat and had access either from outside or from within the house. Something shouted from atop a house would be heard by everyone in the street below.
