'Understand' in the Bible

But Peter, standing with the eleven, raised his voice and addressed them: “Men of Judea and all you who live in Jerusalem, let this be explained to you; listen closely and pay attention to what I have to say.

Moses said, ‘The Lord God will raise up for you a Prophet like me from your countrymen; you shall listen to Him and obey everything He tells you.

And it will be that every person that does not listen to and heed that Prophet will be utterly destroyed from among the people.’
