'Further' in the Bible

“You have taken a firm hold on me and have shriveled me up,It has become a witness [against me];And my leanness [and infirmity] rises up [as evidence] against me,It testifies to my face [about my guilt].

Elihu continued speaking [to Job] and said,

“I have spoken once, but I will not reply again—Indeed, twice [I have answered], and I will add nothing further.”
