'Known' in the Bible

Shallum the son of Col-hozeh, official of the district of Mizpah repaired the Fountain Gate. He rebuilt it and covered it [with a roof], and set up its doors with its bolts and its bars, and [he rebuilt] the wall of the Pool of Shelah (Siloam) by the King’s Garden as far as the stairs that descend [the eastern slope] from [the section of Jerusalem known as] the City of David.

Now when our enemies heard that we knew about their plot against us, and that God had frustrated their plan, we all returned to the wall, each one to his work.

“So You made known to them Your holy Sabbath,And gave them commandments, statutes, and law,Through Your servant Moses.
