'One' in the Bible

Art not Thou of old, O Jehovah, my God, my Holy One? We do not die, O Jehovah, For judgment Thou hast appointed it, And, O Rock, for reproof Thou hast founded it.

Lo, a presumptuous one! Not upright is his soul within him, And the righteous by his stedfastness liveth.

God from Teman doth come, The Holy One from mount Paran. Pause! Covered the heavens hath His majesty, And His praise hath filled the earth.
