'Unreliable' in the Bible

Men are nothing but a mere breath; human beings are unreliable. When they are weighed in the scales, all of them together are lighter than air.

They were unfaithful and acted as treacherously as their ancestors; they were as unreliable as a malfunctioning bow.

You despise all who stray from your statutes, for they are deceptive and unreliable.

An unreliable messenger falls into trouble, but a faithful envoy brings healing.

I will make justice the measuring line, fairness the plumb line; hail will sweep away the unreliable refuge, the floodwaters will overwhelm the hiding place.

They turn to Baal; they are like an unreliable bow. Their leaders will fall by the sword because their prayers to Baal have made me angry. So people will disdain them in the land of Egypt.
