'Uncertain' in the Bible

The Lord has sent among them a spirit of error: and by them Egypt is turned out of the right way in all her doings, as a man overcome by wine is uncertain in his steps.

And further, these are uncertain through wine, and have gone out of the right way through strong drink: the priest and the prophet are uncertain through strong drink, they are overcome by wine, they have gone out of the way through strong drink; their vision is false, they go wrong in their decisions.

Be surprised and full of wonder; let your eyes be covered and be blind: be overcome, but not with wine; go with uncertain steps, but not because of strong drink.
