'Seven' in the Bible

There are six [things] Yahweh hates, and seven [things are] abominations of his soul:

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

For seven [times] the righteous will fall, but he will rise, but the wicked will be overthrown by calamity.

A lazy person is wiser in his eyes than seven who answer discreetly.

When he makes his voice gracious, do not believe him, for seven abominations [are] in his heart.
