'Understand' in the Bible

"So you should understand that [it is] not because of your righteousness [that] Yahweh your God [is] giving you this good land to take possession of it, because {you are a stubborn people}.

Yahweh will raise [up] against you a nation from far [off], from the end of the earth, [attacking] as the eagle swoops [down], {a nation whose language you will not understand},

But Yahweh has not given to you a heart to understand, or eyes to see, or ears to hear, [even] {to this day}.

If only they were wise, they would understand this; they would discern {for themselves their end}.
