'Understand' in the Bible

People of Israel, I'm now bringing a nation from far away to attack you," declares the LORD. "It is an enduring nation, an ancient nation, a nation whose language you don't know. And you won't understand what they say.

Therefore, I'm about to make them understand; this time I'll make them understand my power and strength, so they'll understand that my name is the LORD.

The LORD's anger won't turn back until he has accomplished what he intended to do. In the future you will clearly understand it.

The fierce anger of the LORD won't turn back until he has accomplished and established the plan of his heart. In the days to come, you will understand this.

Indeed, after I turned away, then I repented. And after I came to understand, I slapped my forehead. I was both ashamed and humiliated because I bear the disgrace of my youth.'"
