'Understand' in the Bible

Therefore commit whoredom do your daughters, And your spouses commit adultery, I do not see after your daughters when they commit whoredom, And after your spouses when they commit adultery, For they with the harlots are separated, And with the whores they do sacrifice, A people that doth not understand kicketh.

Who is wise, and doth understand these? Prudent, and knoweth them? For upright are the ways of Jehovah, And the righteous go on in them, And the transgressors stumble therein!
