'Recognized' in the Bible

Judah recognized them, and said, “She is more righteous than I, inasmuch as I did not give her to my son Shelah.” And he did not have relations with her again.

When Joseph saw his brothers he recognized them, but he disguised himself to them and spoke to them harshly. And he said to them, “Where have you come from?” And they said, “From the land of Canaan, to buy food.”

But Joseph had recognized his brothers, although they did not recognize him.
