'Recognize' in the Bible

You will recognize them by their fruits: they do not gather grapes from thorn bushes or figs from thistles, [do they]?

As a result, you will recognize them by their fruits.

But I say to you that Elijah has already come, and they did not recognize him, but did with him whatever they wanted. In the [same] way also the Son of Man is going to suffer [at] their hands."
