'Chance' in the Bible

So she went and came and gleaned in the field behind the reapers. And she happened [by] chance [upon] the tract of field {belonging to} Boaz, who [was] from the clan of Elimelech.

You must watch; if it goes up by the way of its territory to Beth Shemesh, he has caused this great disaster to [come on] us. But if not, then we will know his hand has not struck us; it [was by] chance [that] this happened to us.

Then the people of Israel answered the men of Judah and said, "I have {ten times as much} in the king, moreover in David I have more than you. Why did you treat me with contempt {by not giving me first chance} to bring back my king?" But the words of the men of Judah [were] fiercer than the word of the men of Israel.

I looked again and saw under the sun that the race [does] not [belong] to the swift, the battle [does] not [belong] to the mighty, food [does] not [belong] to the wise, wealth [does] not [belong] to the intelligent, and success [does] not [belong] to the skillful, for time and chance befalls all of them.
