'Acknowledged' in the Bible

For I have known (chosen, acknowledged) him [as My own], so that he may teach and command his children and [the sons of] his household after him to keep the way of the Lord by doing what is righteous and just, so that the Lord may bring upon Abraham what He has promised him.”

And Judah acknowledged them, and said, She hath been more righteous than I; because that I gave her not to Shelah my son. And he knew her again no more.
