'Perplexity' in the Bible

For a day of noise, and of treading down, And of perplexity, is to the Lord, Jehovah of Hosts, In the valley of vision, digging down a wall, And crying unto the mountain.

Their best one is as a brier, The upright one -- than a thorn-hedge, The day of thy watchmen -- Thy visitation -- hath come. Now is their perplexity.
