'Understand' in the Bible

Then he read from it, in front of the open square which was in front of the Water Gate, from early morning until midday, in the presence of the men and women, those who could understand; and all the people listened carefully to the Book of the Law.

Also Jeshua, Bani, Sherebiah, Jamin, Akkub, Shabbethai, Hodiah, Maaseiah, Kelita, Azariah, Jozabad, Hanan, Pelaiah, and the Levites, explained the Law to the people, and the people remained in their places.

On the second day, all of the heads of fathers’ households of all the people, the priests, and the Levites, were gathered before Ezra the scribe to gain insight into the words of the Law (divine instruction).
