'Seven' in the Bible

Here are six things that the LORD hates seven, in fact, are detestable to him:

Wisdom has built her house; she has hewn out her seven pillars.

for though a righteous man falls seven times, he will rise again, but the wicked stumble into calamity.

The lazy person is wiser in his own opinion than seven men who can give an appropriate response.

Though he speaks graciously, don't believe him, for there are seven detestable things in his heart.
