'Chance' in the Bible

For my enemies talk about me; those waiting for a chance to kill me plot my demise.

The wicked have no chance for deliverance, for they do not seek your statutes.

Again, I observed this on the earth: the race is not always won by the swiftest, the battle is not always won by the strongest; prosperity does not always belong to those who are the wisest, wealth does not always belong to those who are the most discerning, nor does success always come to those with the most knowledge -- for time and chance may overcome them all.
