'Bosom' in the Bible

For why should you, my son, be exhilarated with an adulteressAnd embrace the bosom of a foreigner?

Can a man take fire in his bosomAnd his clothes not be burned?

Wisdom rests in the heart of one who has understanding,But in the hearts of fools it is made known.

A wicked man receives a bribe from the bosomTo pervert the ways of justice.

A gift in secret subdues anger,And a bribe in the bosom, strong wrath.
