'Agent' in the Bible

‘But the vine was uprooted in [godly] wrath [by His representative]And it was thrown down to the ground;The east wind dried up its fruit.Its strong branch was broken offSo that it withered;The fire [of God’s judgment] consumed it.

I'm going to inundate Edom with my retribution, using my people Israel to carry it out! They'll deliver my anger, acting as an agent of my fury. Edom will come to know my vengeance,' declares the Lord GOD.'"
