'Have No Knowledge' in the Bible

Moreover your little ones, that ye said should be a prey, and your children, that this day have no knowledge of good or evil, they shall go in thither, and unto them will I give it, and they shall possess it.

Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that carry the wood of their graven image, and pray unto a god that cannot save.

For my people are foolish, they know me not; they are sottish children, and they have no understanding; they are wise to do evil, but to do good they have no knowledge.

If I go forth into the field, then, behold, the slain with the sword! and if I enter into the city, then, behold, they that are sick with famine! for both the prophet and the priest go about in the land, and have no knowledge.

Awake to soberness righteously, and sin not; for some have no knowledge of God: I speak this to move you to shame.
