'Perplexity' in the Bible

For it is a day of trouble, and of treading down, and of perplexity by the Lord GOD of hosts in the valley of vision, breaking down the walls, and of crying to the mountains.

The best of them is as a brier: the most upright is sharper than a thorn hedge: the day of thy watchmen and thy visitation cometh; now shall be their perplexity.
