'Utter' in the Bible

While boasting of their wisdom they became utter fools,

Without becoming weak in faith he considered his own body, now as good as dead [for producing children] since he was about a hundred years old, and [he considered] the deadness of Sarah’s womb.

So I say, have they stumbled so as to fall [to spiritual ruin]? Certainly not! But by their transgression [their rejection of the Messiah] salvation has come to the Gentiles, to make Israel jealous [when they realize what they have forfeited].
