'Understandest' in the Bible

And Pharaoh said to Joseph, I have dreamt a dream, and there is none to interpret it. And I have heard say of thee, thou understandest a dream to interpret it.

Jehovah will bring a nation against thee from afar, from the end of the earth, like as the eagle flieth, a nation whose tongue thou understandest not;

What knowest thou that we know not? what understandest thou which is not in us?

Thou knowest my down-sitting and mine uprising, thou understandest my thought afar off;

Behold, I bring a nation upon you from afar, house of Israel, saith Jehovah: it is a mighty nation, it is an ancient nation, a nation whose language thou knowest not, neither understandest thou what they say.
