'Behalf' in the Bible

"As for you, don't pray on behalf of this people, don't cry or offer a petition for them, and don't plead with me, for I won't listen to you.

Should good be repaid with evil? Yet they have dug a pit to take my life. Remember! I stood before you and spoke good on their behalf in order to turn your wrath away from them.

"Please inquire of the LORD on our behalf, because King Nebuchadnezzar of Babylon is fighting against us. Perhaps the LORD will do some of his miraculous acts for us, and Nebuchadnezzar will depart from us."
