'Deep' in the Bible

The way of the wicked is like [deep] darkness;They do not know over what they stumble.

“When He established the heavens, I [Wisdom] was there;When He drew a circle upon the face of the deep,

When He made firm the skies above,When the fountains and springs of the deep became fixed and strong,

The words of a man’s mouth are like deep waters [copious and difficult to fathom];The fountain of [mature, godly] wisdom is like a bubbling stream [sparkling, fresh, pure, and life-giving].

Laziness casts one into a deep sleep [unmindful of lost opportunity],And the idle person will suffer hunger.

A plan (motive, wise counsel) in the heart of a man is like water in a deep well,But a man of understanding draws it out.

The mouth of an immoral woman is a deep pit [deep and inescapable];He who is cursed by the Lord [because of his adulterous sin] will fall into it.

For a prostitute is a deep pit,And an immoral woman is a narrow well.
