'Doing' in the Bible

You know that Abner the son of Ner came to deceive you. He came to learn about your going out and coming [in] and to know all which you [are] doing."

I [am] weak today even though anointed king, and these men, the sons of Zeruiah, [are] crueler than I [am]. May Yahweh pay them back for doing wickedness according to their [own] wickedness."

Why have you despised the word of Yahweh by doing evil in his eyes? Uriah the Hittite you have struck down with the sword, and his wife you have taken to yourself as wife! You have killed him with the sword of the {Ammonites}!
