'Happens' in the Bible

But he does not have a root in himself, but {lasts only a little while}, and [when] affliction or persecution happens because of the word, immediately he falls away.

And if he happens to find it, truly I say to you that he rejoices over it more than over the ninety-nine that did not wander away.

And he also said to the crowds, "When you see a cloud coming up in the west, you say at once, 'A rainstorm is coming,' and so it happens.

And when [you see] the south wind blowing, you say, 'There will be burning heat,' and it happens.

From now [on] I am telling you before [it] happens, in order that when [it] happens you may believe that I am [he].

And now I have told you before [it] happens, so that when it happens, you may believe.
