'Understand' in the Bible

And he read therein before the street that was before the water gate from the morning until midday, before the men and the women, and those that could understand; and the ears of all the people were attentive unto the book of the law.

Also Jeshua, and Bani, and Sherebiah, Jamin, Akkub, Shabbethai, Hodijah, Maaseiah, Kelita, Azariah, Jozabad, Hanan, Pelaiah, and the Levites, caused the people to understand the law: and the people stood in their place.

So they read in the book in the law of God distinctly, and gave the sense, and caused them to understand the reading.

And on the second day were gathered together the chief of the fathers of all the people, the priests, and the Levites, unto Ezra the scribe, even to understand the words of the law.
